APEC 2020 Finally Returns to New Orleans After 32 Years

B uilding upon the very successful APEC2019 in Anaheim, the APEC2020 will take place for the first time since 1988 in New Orleans. Our initial return visit, planned for 2005, was undermined by Hurricane Katrina. Fortunately, we were able to relocate that year's event to Dallas.  A lot have things have changed since that APEC in 1988.  Back in the 1980s, APEC took place in hotel meeting rooms with a small ballroom exhibit. Since then, APEC has grown to be the unrivaled venue for the Power Electronics Industry and our industry has emerged to its rightful place as enabling many of the advances in electronics technology. Back in 1988, a competitive power supply had an efficiency of maybe 85%, today we are discussing supplies with 98% efficiency.  Back then, we had APEC attendance that numbered in the hundreds. In 2019, we had over 6,000!

Technical Sessions - Now Open

Submissions of technical papers for consideration are due by late July. (Right now, the date is July 19, but this is subject to change.) Prospective authors are asked to submit a digest explaining the problem that will be addressed by the paper, the major results, and how this is different from the closest existing literature. Papers presented at APEC must be original material and not have been previously presented nor published. The principal criteria in selecting digests will be the usefulness of the work to the practicing power electronic professional. Reviewers value evidence of completed experimental work.  Go here for more information and submission details:

Professional Education Seminars – Opens in Early July

Professional Education Seminars at APEC2020 will address the need for in-depth discussion of important and complex power electronics topics. Submission are due by early September. Seminars are three-and-a-half hours (including breaks) in length, can range from broad to narrow in scope, and can vary from introductory to advanced in technical level. Topics selected are to address the practical issues of the specification, design, manufacture and marketing of power electronic components, products, and systems. Visit the APEC website to find out more information when available.

Industry Sessions – Opens in Early July

The Industry Sessions run in parallel with the technical sessions and have proven to be very popular. Submissions are due by early September. Speakers are invited to make a presentation only without submitting a formal paper. The target audience for these sessions differs from the engineers in typical technical sessions and may include system engineers/architects and business-oriented individuals such as purchasing agents, information technologists, regulatory agencies, and others who support the power electronics industry. Visit the APEC website to find out more information on the program when available.

Make your plans to be part of APEC2020. Be sure you have this important event on your calendar and included in your budget for next year. And do your part to make it an even better conference by volunteering to be on the technical paper peer-review panel in areas where you are qualified. 

See you in New Orleans – Laissez Bon Temps Roule.

W. L. Gore & Associates, Inc.

A privately held company with $3.5 billion in annual revenues, W. L. Gore & Associates (Gore) pursues opportunities where our core technologies and deep technical expertise make a meaningful impact. Gore delivers breakthrough solutions to product and process challenges in a variety of markets and industries — from aerospace to pharmaceutical to mobile electronics, and more. The wide range of Gore products includes hook-up wire to power challenging systems in military aircraft and downhole tools, navigation and communication cables for missions to Mars, fuel cell components that enable cleaner, greener transportation and power generation, venting solutions to manage the internal pressure in mobile electronics and automotive components enclosures, and cable integrity technologies for 5G applications. Our specialized medical devices treat a range of cardiovascular and other health conditions.

Gore has 9,500 Associates, with manufacturing facilities in the United States, Germany, United Kingdom, Japan and China, and sales offices around the world.

In 1958, Bill and Vieve Gore launched W. L. Gore & Associates in the basement of their Delaware home to explore the untapped potential of the polymer polytetrafluoroethylene, or PTFE. The company's first product was MULTI-TET™ Insulated Wire and Cable. It was used most widely in defense applications and in the burgeoning computer industry. In the 1960s, the company's first patent was issued and Gore's technology landed on the moon as part of NASA's historic Apollo 11 mission.

In 1969, the couple's son, Bob Gore, discovered how to modify PTFE to form a strong, porous material. This invention —expanded PTFE or ePTFE — changed the future of the enterprise and paved the way for waterproof, breathable GORE-TEX® fabric and thousands of diverse innovations.

As the company that invented ePTFE and introduced it in the marketplace, Gore remains a fluoropolymer leader, committed to engineering excellence and building on our founders' tradition of using advanced materials to improve lives and change outcomes for customers and end users around the world.

GORE™ High Temperature Capacitors are primarily used as DC-Link capacitors in challenging power electronic applications. Unlike other polymer film capacitors which typically are limited to 120°C operating temperature, GORE™ Capacitors have proven capable up to 250°C. With the introduction of wide bandgap semiconductors (SiC and GAN), the lack of suitable high temperature capacitors has become an increasingly difficult challenge for system designers. Designers are faced with adding significant design complexity or limiting system performance to prevent the capacitors from overheating. GORE™ High Temperature Capacitors will allow designers to significantly improve the total system efficiency and allow film capacitors, known for reliability, to be used in applications not possible in the past.

GORE™ High Temperature Capacitors are gaining widespread commercial use in oil and gas downhole tools with the major global oilfield service companies. Additionally, several leading aerospace design companies are qualifying GORE™ High Temperature Capacitors for multiple commercial and defense applications supporting more electric aircraft (MEA) and future all-electric aircraft programs.  With the electrification mega-trend, further adoption will only accelerate as additional complementary technologies are advanced and new systems are qualified.

Remembering Charles "Chuck" Edwin Mullett

Chuck Mullett, Apr 25, 1938 – Mar 18, 2019

O n 18 March 2019, Charles "Chuck" Edwin Mullett, of Santa Paula, California, passed away peacefully at age 80.  He was born in Buffalo, New York, to the late Sarah (Hill) Mullett and the late Charles Beatty Mullett.

Mullett grew up in Bremerton, Washington where his father was a naval officer. He graduated from the University of Illinois at Urbana-Champaign with a Bachelor of Science in Electrical Engineering in 1960, and a Master of Science in 1962. In college, he was the president of his fraternity Alpha Chi Rho and was in several music bands. Soon after graduating he moved to Southern California where he had a long and rewarding career designing power electronics.

For more than 20 years, Chuck owned and operated Mullett Associates, Inc., a design consulting firm, and eventually worked at ON Semiconductor from where he retired in 2013. He was granted nine patents, and was a speaker of note in several professional organizations He also founded the Los Angeles Chapter of the IEEE Power Electronics Society (PELS) and served as the APEC Chair in 1996. His magamp post regulation design was leading the industry in mid-1990's.

Mullett was an active member of Santa Paula Rotary, and enjoyed sailing and amateur radio, and was known for his optimism, drive, enjoyment of people, and a zest for life. He enjoyed playing clarinet and saxophone, playing locally in six bands.

Chuck was a strong contributor and supporter of PSMA for more than 20 years serving for 6 years on the PSMA Board of Directors including President and Chairman. He was Co-Chair for the 2003 and 2006 Power Technology Roadmap Report and the author of the popular PSMA Handbook of Standardized Terminology For the Power Sources Industry. Chuck was a supporter of the NanoTechnology initiative at PSMA and a mentor for many in the industry. Chuck was a member of the PSMA Advisory Council until his passing. Remembrances from some PSMA members and supporters are included below.

Chuck was the beloved husband, for 50 years, of Vivian and we offer our condolences to her and his family. May He Rest in Peace.

I met Chuck in mid-eighties (1985?) at some show before PSMA. Both of us had our own consulting businesses: Micro-Tech Consultants, a market research consulting business and Chuck with Mullett Associates, a power electronics design consulting business. Our businesses were complementary, so we decided to 'collaborate' in bringing clients to each other with a 10% finders' fee. We did bring any client to each other, but due to our mutual interest in the power electronics business and the PSMA we remained good friends forever. We worked on some projects together and participated in many meeting. Chuck was my original friend in the power electronics and I will miss him dearly. (Mohan Mankikar, Micro-Tech Consultants, PSMA Advisory Council)

Chuck touched me in many professional and personal ways. We worked together a PSMA projects and he and his darling wife, Viviane, were wonderful hosts on the occasions when I would stay at their home in Santa Paula. A sweet, gentle man. I was blessed to call him friend. (Greg Evans, WelComm, PSMA Marketing Committee Co-Chair)

Chuck Mullett, Tony Laviano and Ernie Parker at APEC 2013 Nanotechnology Committee Meeting
I met Chuck through PSMA when he worked at ON Semiconductor and I worked at International Rectifier. We were competitors for the same business, yet I immediately found a kindred spirit who believed there was enough business for everyone and that we all benefitted from a stronger Power Supply Industry. We became good friends who enjoyed working together on projects for the good of the industry. I learned a great deal from Chuck during his collaboration on the Roadmap and his fantastic ability to proof the late versions of the total Roadmap in order to correct the punctuation and use of acronyms as well as the spacing of numbers and units of measure. His insight into how power semiconductors worked within power supplies lead the industry. (Carl Blake, CBK, PSMA Advisory Council)
Two words that summed up Chuck's approach to everything he did – passion and dedication. In all the years I had the privilege of knowing Chuck, I've never seen him without those qualities – even for a minute. I used to interact with Chuck at many PSMA sponsored activities (probably going back to mid-90's). He was one of the reasons I decided to move to ON Semi in early 2000's. After that, we interacted very frequently and it was a privilege being able to talk to him almost every day and learn from him. We have traveled all over the world together and the stories from those travels could fill pages. I remember he came to India once and he wanted to visit the local Rotary club meeting – he went and gave them a nice talk, but whatever he ate/drank there made him sick. Despite the sickness, he was game enough to carry through with other planned activities rest of his trip. At work, his passion was most evident in adhering to the IEEE writing guidelines. Outside work, he loved his music and sailing and his family. I was lucky enough to see him last October when he drove down in his Tesla to Anaheim during APEC planning meeting. At that time, Chuck mentioned that Vivian thinks that he flunked retirement! Well, he may have flunked retirement, but he definitely aced life. (Dhaval Dalal, ON Semiconductor, PSMA Board of Directors)
I first met Chuck years before his company became a member of PSMA. He offered his services and advice on a number of projects and, after he changed employers, convinced his new company to become a member. He was always ready to dig in and contribute to and lead many projects including the Roadmap, updating the Handbook of Standard Terminology, organizing the Nanotechnology Initiative, supporting APEC and making the Association stronger. I remember Chuck as an outstanding individual of high character, very smart, very high energy and over the years as a cherished friend. It was always a treat to hear about his sailing exploits and music gigs. May He Rest in Peace. (Joe Horzepa, Executive Director, PSMA)

Chuck Mullett and Joe Horzepa at APEC 2013
Chuck Mullett and I were Co-Chairs of the Nanotechnology Forum. Chuck was a true champion of nanotechnology for power supplies but not at first. Chuck was skeptical, unconvinced, and kept challenging me to show him how nanotechnology could be used for power supplies. But he figured it out. Then he asked me to be his Co-Chair of the PSMA Nanotechnology Forum to introduce nanotechnology applications to the PSMA Membership and APEC. We became a three-legged team so I would not drag my feet. Chuck saw both his visions come true. PSMA developed Nanotechnology tutorials for its members. Then in 2010 he introduced nanotechnology to APEC. I was the PSMA Nanotechnology Plenary Speaker and Chuck lead APEC's first Industry Nanotechnology Session which continued for six years under his leadership. Chuck Mullett was a visionary who was committed to the professionalism of PSMA. His nanotechnology legacy is not lost. It is in the PSMA Education Forum under Resources. Chuck figured it out! (Tony Laviano, NRAIT, PSMA Nanotechnology Committee Co-Chair Emeritus)

Chuck Mullett and Dr. Anthony F. Laviano Kicking off the Nanotechnology Forum at the 2012 PSMA Annual Meeting
I met Chuck when I took on the global applications engineering team and systems engineers at ON semi. Chuck worked for me and taught me a great deal. This was right about the time everyone was asking 'what does a systems engineer do? what does a FAE do? - you know finance and operations took over all aspects of everything during that time. Once they saw Chuck in action nobody asked what the ROI was or what does a Chuck do... ever again. Chuck made thing look easy because they probably were to him, he solved complex problems for customers, designed circuits and defined new products. He accepted nothing less than excellence in all that he did and wanted to make things better and improve the process all the time. Chuck was responsible for getting me into PSMA and involved with APEC and he also was one of the IEEE members who recommended me for IEEE Senior Member. Chuck had a great way of cutting through complexity and getting to the core issue of a problem and then setting about to solve it. He was a great mentor and friend to everyone around him. He helped me too many times to count and as an employee he always did more than expected of him. The laughs and fun on trips to China and Taiwan I will never forget the times and the stories. Chuck made a significant positive difference in the industry, in the lives of people everywhere and I benefited personally having known him. He was a great friend who I miss greatly he is probably proofreading technical documents and playing the sax in heaven and having a great time. (Kevin Parmenter, Taiwan Semiconductor, PSMA Board of Directors)

International Workshop on Integrated Power Packaging (IWIPP) 2019

T he 2019 International Workshop on Integrated Power Packaging (IWIPP) was held the LAPLACE CNRS, Toulouse, France, April 24-26, 2019.  Dr. Thierry Lebey the Director and General Chair of the workshop welcomed us to Toulouse on the first day.  Attendance was up 30% compared to 2017 (94 registered attendees in 2019 vs. 72 in 2017).  This increase in interest probably reflects the importance of improved power electronics packaging for more efficient power through many industries.  There was a significant international representation; approximately 50% of attendees from Europe, 35% from the US, and 15% from Asia.

IWIPP 2019 Attendees

The technical program this year was very strong with positive feedback from audience members that indicated that the program exceeded expectations for content quality.   Since Toulouse is the center of the European Aerospace Industry it is not surprising that many of the presentations were related to the Electrification Challenges in Aeronautics.  These were reviewed in a Plenary by Dr Christophe Lochot of Airbus.  Although this gave us an insight into these issues, one of the core characteristics of IWIPP is that it has always been a multi-disciplinary workshop and this year was no exception.  Power packaging design requires expertise from a range of engineering disciplines; including electrical, thermal, mechanical, and materials.  Attendees were exposed to all aspects of power electronics packaging over a wide range of interdisciplinary research.  The use of wide band gap semiconductors and the challenges these present for packaging were discussed by many presenters.  Dr Ty McNutt of Wolfspeed gave a tutorial on System Level Reliability for SiC Power Modules and Dr. Ahmed Elasser of GE Global Research reviewed the history and future prospects for SiC.  The critical packaging design aspects associated with higher switching frequencies and temperatures were reviewed in depth.   Dr. Aaron Brovont of the University of Alabama gave a tutorial on assessing EMI in power electronics and novel approaches to thermal management were reviewed by Dr. Ercan Dede of Toyota.  As power packaging becomes more critical to Aerospace and Automotive Industries understanding reliability is extremely important and the origins of these limits were described by Dr. Laurent Dupont IFSTAR-SATIE in his Plenary presentation.

Many of the oral presentations described various approaches to enhancing performance through improved packaging materials and better circuit designs.  Several different developments were described in detail including the use of aluminum metallized silicon nitride substrates as well as the increasing use of sintered metal and transient liquid metal interconnects.  The performance of coatings for very high voltage insulation was reviewed in detail. Packaging passive components to achieve higher power densities whilst reducing parasitic inductance and resistance was reviewed in some of the presentations. 

In addition to presentations by leaders from academia and industry students also presented their work in oral and poster presentations.  To encourage student participation to present their research findings and cultivate interest in packaging technologies among the next generation of engineers IWIPP 2019 offers a Student Travel Grant Award  In 2019 this was won by Brian T. DeBoi of the University of Alabama who presented work on Bus Snubber Optimization for Multi-Chip Power Modules supervised by Dr Andrew N. Lemmon. Brian's research focuses on improving frequency-domain characterization and behavioral die modeling methods of silicon carbide utilizing devices and their surrounding packaging. These improved models and parasitic estimations can be leveraged in simulation to better understand what parameters are most impactful on device behavior, and to devise techniques to improve performance of real-world systems.

There were plenty of networking opportunities at the poster session at the several benchtops exhibits and during the tours of the Power Electronics & Integration, Smart Grid & Emulation and Actuation & Electroactive Morphing Laboratories.  Discussions continued through the Banquet Dinner sponsored by Wolfspeed (Diamond Level Sponsorship).  The high-quality food and wine provided during the Banquet and meetings probably set a new benchmark for the workshop.

Additional sponsorship was provided by Littelfuse and KEMET (both at Platinum Level) and Heraeus (Gold Level Partner).  This workshop was endorsed by IEEE Power Electronics Society, IEEE Electronics Packaging Society, IEEE Dielectrics and Insulation Society, Power Sources Manufacturers Association, the European Center for Power Electronics and Power Sources Manufacturer's Association This broad participation of academia and industry resulted in a multi-disciplinary event to present and discuss innovative solutions to address the challenges of power packaging in many applications.  Planning will begin soon for IWIPP 2021 that will expand this commitment to the power packages of tomorrow.  People interested in helping to organize for 2021 can just reach out to Dr. Andrew Lemmon at

Arizona State University's SkySong Innovation in Scottsdale, AZ
October 31 – November 1, 2019

The Power Sources Manufacturers Association (PSMA), in partnership with IEEE Power Electronics Society (PELS), is sponsoring a Phoenix Workshop on Packaging and Integration in Power Delivery at Arizona State University's SkySong Innovation in Scottsdale, AZ October 31-Nov. 1, 2019. This two half-day event is An Exploratory Workshop Leading to the 2020 International Workshop on Power Supply on Chip (PwrSoC), in Philadelphia, PA.

The workshop will focus on the integration of miniature solid state power converters in microelectronics package environment, which attracted increasing interest in recent years as electronic devices overall form factor have scaled down significantly in a broad range of applications and power levels. In particular, strategies on how to integrate power delivery in package (PSiP) with more efficiency, smaller form factor, will be one of the focuses of the workshop. The other focus is on how to fit power delivery function into multi-die situation. These will involve the active discussions between IC designers, assembling experts and substrate/materials providers to provide innovative solutions to address power delivery in package challenges.

The workshop will be held at Arizona State University's SkySong Innovation in Scottsdale, AZ. The General Chair is Professor Hongbin Yu from ASU's School of Electrical, Computer and Energy Engineering, who has participated in many of the prior PwrSoC workshops, and the Technical Program Chair for the workshop is Jim Doyle from Dialog Semiconductor, who presented a keynote speech at the PwrSoC2018.

Knowing the Link Between Product Regulations and Product Standards Can Put You Ahead of the Competition

M aintaining the Power Sources Manufacturers Association (PSMA) Energy Efficiency Data Base (EEDB) and the Safety and Compliance Data Base (SCDB) has given me the unique opportunity to track and understand the relationship between the product regulations in the EEDB and product standards in the SCDB.

A regulation is a rule or directive created and maintained by an authority such as a country, federation of countries, states, or provinces. Enforcement is by law. Content is available to the public for free.

A standard is a document created by consensus and approved by a recognized body or organization for common or repeated use. Standards may be international or regional. Most standards are available to the public for a fee levied by the organization. Enforcement occurs when a label is attached to the product indicating compliance.

Regulations precede and influence the certain performance and test standards. This article explains how company standards staff and design engineers can monitor and influence a regulation far in advance of any standard(s) creation thus better positioning their company products for success under the new regulation.

Beginning with a historic example, I chose the European Union (EU) and the relationship between the Ecodesign efficiency regulation and the relevant IEC standard(s), I find that they have the clearest and most easily understood creation process. Once the regulation/standard association is covered, then we will see how it applies to the next regulation upgrade now commencing. Everything explained here applies to creative processes in the U.S. and other countries using the organizations and processes of those countries. The U.S. processes will be covered in a future article.

Why Regulation Tracking Is Important
The EU target power consumption reduction translates into the required performance of a multitude of energy-related products (ErPs). EU Parliament in their DIRECTIVE 2009/125/EC established the framework for Ecodesign creating a framework for more than 35 lots with each lot having one or two appliances. Ecodesign legislation listing all of the energy-related products is shown in reference 1[1]. In 2009, Ecodesign Lot 7 (CELEX:32009L0125)[2] contained both EPS and small battery chargers. We will focus on the EPS.

EU Regulation Development
The regulation creation process is very slow. Comprised of five steps and conducted over several years, it allows a supplier adequate time to prepare products for compliance with the new regulation.

Action 1: The EU Commission assigns a team of analysts, both commission staff and consultants, to determine the energy consumption level reduction needed.

Action 2: The EU targets are then translated into product performance (in this case, efficiency) by Ecodesign teams. European Parliament Directive 2005/32/EC established the five process Ecodesign steps shown in Fig. 1. Using these steps, the Ecodesign team develops the efficiency performance requirements for an ErP adequately contributing to the overall EU power consumption level target.

Fig. 1. Ecodesign process steps.

The Ecodesign Lot 7 team determined EPS power consumption could best be reduced by focusing on a) the no-load electric energy consumption and b) the average active-mode efficiency. Executing the five steps in Fig. 1, they arrived at the approved minimum efficiency levels that were passed into law as a part of EU COMMISSION REGULATION (EC) No 278/2009 on April 6, 2009.[3]

Table 1 from that regulation established the acceptable performance limits in terms of no-load power consumption and average active efficiency. (Note: Table 1 refers to low-voltage external power supplies. Low voltage is defined in Article 8, paragrah 2 as less than 6-V output voltage, and more than 550-mA output current.)

Table 1. 2011 external power supply minimum performance limits.

The document that identifies the associated standard from which the test procedure is derived is EU Document 52015XC0415 (01)[4] with an extensive title referred to in the reference. (Note that publication titles and references of harmonized standards are applicable under EU harmonization legislation.) Table 2 from that document identifies the associated Standard EN50563-2011 with first publication in 2013. (Note that maximum no-load power consumption was first established by U.S. Executive Order 13221 July 31, 2001.)

Table 2. From EU Commission communication: Coupling is identified between the standard EN 50563 test procedure and the EPS efficiency regulation. (Implementation – 2015/C 120/02).[5]

Associated IEC Standard
The standard associated with the regulation may be any type including a performance standard, or a test standard. In this example, IEC 50563 is a test standard.[6] This standard creation is not historically accurate but is estimated to have started by a European Committee for Electrotechnical Standardization (CENELEC) team in 2008.

Ecos Consulting initially developed the equations in Table 2 during California Energy Commission (CEC) and Energy Star work in 2003 and subsequently modified them in 2006 and 2007 during further CEC efficiency regulation test procedure work. The equations were later adopted by Ecodesign during their harmonization efforts in the 2008/2009 time frame.

Development Timeline
The advantage of monitoring the regulation prior to start of commencing the standard creation becomes clear when the time-line of these two documents is illustrated in Fig. 2. Following the timeline figure, the regulation establishing the process was started in 2005. Subsequently, the standard EN 50563 development commenced a year or so before the conclusion of the Ecodesign Lot 7 regulation work in 2009. So, the regulation development work occurred very early compared to the standard work.

By participating in or at least monitoring the regulation performance development, a one-year advantage was available to the manufacturer to prepare their product for compliance and competitive positioning. Issued in 2011 and becoming effective in 2015, the standard EN 50563 set the final EPS testing procedure for an efficiency performance product in compliance with the Ecodesign Lot 7 regulation.

Fig. 2. Timeline for regulation example and the associated standard.

Better Prepared
A supplier company, heeding the advice of their standards engineer, would normally take advantage of the multi-year standard creation work by participating in or monitoring the action of the standards committee. However, the timeline illustrates that there is even greater advantage to be realized by being involved in or cognizant of the regulation creation process.

Next Phases
What about present efficiency regulations and standards? Many suppliers incorrectly believe that the 2005-to-2015 sally of energy efficiency regulations and standards is over, requiring no further compliance effort. But that is not the case. Regulation creation is an ongoing process as shown for this efficiency regulation case with government and non-government agencies seeking to continue reductions in power consumption.

However, by directive the EU continues to raise the efficiency bar. They are using projected power consumption for the year 2016 to determine future required energy consumption reductions for the next decades. The EU has negotiated the targets of 20% reduction by 2020, and 32.7% by 2030[7] with all countries and their experts. (Note that other countries are doing the same. Countries' targets may vary so check those countries for which you have concerns about product acceptance. Even states and provinces sometime set their own aggressive goals.) [8,9]

Their seriousness is reflected by the following statement: "The revised Energy Efficiency Directive (EU) 2018/2002 (Energy Efficiency Directive (EU) 2018/2002 )[8] sets a 2030 target of 32.5%, also with a possible upward revision in 2023. The new Governance Regulation (EU) 2018/1999 includes the requirement for Member States to draw up integrated National Energy and Climate Plans for 2021 to 2030 outlining how to achieve the targets and submit the draft to the European Commission by the end of 2018".[10]
Fig. 3 illustrates Phases 2 and 3 creating the Ecodesign EPS regulation for 2020 and 2030 respectively. Since EN 50563 is a test standard not a performance standard, very little if any update will be required as this standard is used in Phases 2 and 3. In this instance, all attention should be on the developing regulation.

If the associated standard had covered EPS performance, that standard would need updating in the later phases following the requirements dictated by the subsequent regulations. Phase 1 depicts the original regulation work effective 2015. The present 2020 update is in Phase 2. The future 2030 work is covered in Phase 3. In each case, the first step is creating the regulation target followed by the determination of the Ecodesign appliance-specific performance.

Fig. 3. Timeline for regulation example and associated standard through 2030.

In this article, we have shown that there sometimes is a link between a regulation and a standard. Our example, taken from the EU history for the EPS product regulation, clearly identifies that there is regulation development occurring several years before the associated standard development. Knowledge of this link is priceless when working to achieve product compliance and maintain a competitive advantage.

A final note: sometimes even earlier work will provide insight into regulation content. The equations in Fig. 1 were first derived in 2003 by Ecos Consulting for the California Energy Commission. These equations were subsequently improved through the efforts of CEC, Energy Star, and the EU. Those involved in this early work gained almost a decade of advantage on their competitors.

RoHS 3 - The new Directive is effective July 2019!

A s specified in the European Directive 2015/863 beginning the 22nd of July 2019, electronic equipment manufacturers will have to comply with the third revision of the Restriction of Hazardous Substances (RoHS), referenced as RoHS 3. All categories of electrical and electronic equipment are affected except medical devices and monitoring and control instruments, which have until 22 July 2021 to comply to take into account their longer innovation cycles. The "Revision 3" adds four additional restricted substances, listed under phthalate, to the original list of six (see table 1).

Table 2 – The four banned phthalates are widely used across the whole industry

In 2010 some phthalates were on the REACH candidate list or listed in REACH Annex XIV as subject to the authorization process. They were also included in the European Commission's proposal for the recast of the EU Directive on the restriction of hazardous substances (RoHS) in electrical and electronic equipment as priority substances to be assessed for potential restriction. Eight years later, this is now happening.

Since the original listing in REACH, and in the candidate list of Substances of Very High Concern for authorization (SVHC), the risk and toxicity of the four substances, listed below, have been researched by international laboratories.

  • Bis (2-ethylhexyl) phthalate (DEHP)
  • Benzyl butyl phthalate (BBP)
  • Dibutyl phthalate (DBP)
  • Diisobutyl phthalate (DIBP)

The results of more than 10 years of testing and investigation exhibit a very high hypothesis that the effects of exposure to phthalates may affect human reproduction, development and risk of cancer. These results have motivated the European Commission to move the four phthalates from "Observation" to "Restriction and Interdiction".

Phthalates are a group of chemical substances used to soften and increase the flexibility of plastic and vinyl. They are commonly used in all industries from food packaging to cables, in insulation tapes and in some resins, in short they are almost everywhere (see table 2).

This is yet another new challenge for the electronics industry which after reducing the amount of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers, is now further tasked with reducing the amount of the four listed Phthalates to below 1000 ppm in homogeneous material by weight.

Table 1 – From RoHS 1 to RoHS 3

On the way to compliance

As was the case for the previous six restricted substance in RoHS 1st edition and RoHS 2nd edition, due to the high usage of phthalates in electronics equipment - including in power supplies,  designers must work in close cooperation with their suppliers to substitute such materials with "phthalate free" elements and components.

Since some industries (e.g. medical) are more sensitive to the risk of phthalates affecting people (patients), as long ago as 2010 they were informing and educating their suppliers about the forthcoming regulations, anticipating the demand for parts with less than 1000 ppm of the identified substances listed in REACH and SVHC.

Today, a number of companies are offering RoHS 3 compliant substitutes but there is a huge lag in the supply chain which will require some pretty intense work to ensure that all products delivered after 22nd July are compliant. For newly made products, this might not be a major problem, but it could be for products held in stock all over the world.

Are my products complying and what about legacy?

Since the European Directive 2015/863 was released the 31st March 2015, designers have worked with their suppliers to guarantee that all new products pre-comply with the forthcoming regulation, but in some case it has been difficult to replace certain parts (e.g. insulation tape for high voltage transformers), thus delaying the compliance of some products. In three years' time suppliers will have implemented different processes and substances to replace banned phthalates, but there are few questions remaining on special components or parts.

However, if the level of banned phthalates in new products is reduced to below 1000 ppm, the doubt remains for items laying in stock. To be on the safe side, a number of companies have made the decision to run samples through an X-Ray Fluorescence (XRF) analyzer, and if this is not deemed enough to use Fourier Transform Infra-red Spectroscopy (FTIR) testing methods and sometimes Scanning Electron Microscopes (SEM).

The cost for such analysis could be substantial however, in the context of present day market conditions and the effects of component shortages, scraping products without knowing if the level of the four phthalates is below or over the 1000 ppm threshold might cost even more money.

Repair and maintenance, what should I do?

As specified in the Directive, the restriction of DEHP, BBP, DBP and DIBP shall not apply to cables or spare parts for the repair, the reuse, the updating of functionalities or upgrading of capacity of electrical and electronics equipment placed on the market before 22 July 2019, and of medical devices, including in vitro medical devices, and monitoring and control instruments, including industrial monitoring and control instruments, placed on the market before 22 July 2021.

RoHS-1, RoHS-2, RoHS-3, what's next?

"REACH aims to improve the protection of human health and the environment through the better and earlier identification of the intrinsic properties of chemical substances." That means that research on toxicology and its impact on health and the environment will continue in order to identify risks.

As well, the European Chemical Agency has worked on a "Roadmap for SVHC identification and implementation of REACH Risk Management measures from now to 2020" which gives an EU-wide commitment to ensure that all relevant, currently known substances of very high concern (SVHC) are included in the candidate list by 2020. The objective of the SVHC Roadmap is to screen to identify new substances of concern, and to analyze the risk management options (RMO) appropriate to the particular substance of concern.

In today's business environment, electronics engineers must permanently monitor the evolution of REACH and SVCH. With the growing concerns about health and the environment we can expect more substances to be added to the RoHS list, which in some cases may prove to be extremely challenging.

As in many other situations, knowing your industry, being innovative and investing in new technologies is probably the only way to go.
