APEC Returns to Southern California – See You in Anaheim, March 17-21, 2019

T he 2019 Applied Power Electronics Conference, which will convene March 17-21 at the Anaheim Convention Center continues the longstanding tradition of addressing issues of immediate and long-term interest to the practicing power electronics engineer. This annual event is jointly sponsored by the IEEE Industry Applications Society (IAS), IEEE Power Electronics Society (PELS), and Power Sources Manufacturers Association (PSMA). The event seems to set records every year for the number of papers, the size of the exhibit and the number of attendees. It must be noted that APEC continues to be an exceptional bargain with full registration for under $1,000. Registrations will be open right after Labor Day. In the meantime, please visit the website (https://www.apec-conf.org/) to find out about speaking opportunities for the technical sessions, industry sessions and other ways you can be part of APEC2019.

 "APEC allows power electronics professionals from all sectors to gather annually and participate in a rewarding exchange of technical knowledge and gaining valuable industry connections," said APEC 2019 General Chairman, Ernie Parker. "I look forward to APEC every year as a time to meet colleagues, see what new directions are emerging in our field, and find new solutions to the problems or sometimes find new problems to solve."

The Call for Papers for APEC 2019 will open in June, check the APEC website for more information.


Meanwhile, APEC 2018 set an all-time record for the number of full-conference registrations. In addition, the Sunday and Monday Professional Education Seminars were exceptionally well attended, as were the two PSMA-sponsored pre-APEC daylong workshops on magnetics and capacitors.  What is clear is the rapid emergence of advanced technology power switching devices is adding to the need for knowledge and application insights. APEC is the ideal forum for engineers to acquire this valuable information. 

A new feature of APEC2018 was the live-streaming of all six plenary sessions. An on-demand version of the plenary session is available here: https://ieeetv.ieee.org/event-showcase/apec-2018. Register here in order to receive PDF files of the speakers' slide decks.

With the conference returning to Southern California, we are expecting attendance to exceed 5,000. The tradeshow has already sold-out with 261 exhibitors signed up and over 100 others on the waiting list. It's not too early for you to make plans to attend…mark your calendars.

EnerHarv – A new ecosystem for energy harvesting and micro-power management

T he 'powering the Internet of Things' market is set to explode with a recent McKinsey study reporting an estimated one trillion IoT devices globally by 2025. All of these devices need a power source representing unprecedented opportunities for the power electronics community. This includes designing parts and systems with lower power consumption & higher energy storage, smarter and context aware energy management devices and potentially the use energy harvesting and related technologies to eliminate the need for battery placement. This has led to the formation of the PSMA EnerHarv 2018 workshop, 'a focal point for a community of experts and users of energy harvesting & related technologies to share knowledge, best practices, roadmaps, experiences and create opportunities for collaboration.'

 

In the First Quarter 2018 edition of PSMA Update we brought exciting news on the initial launch of EnerHarv 2018 with an outline agenda and keynote speakers from TI & Imperial College London. The committee has since then defined the detailed agenda, lining up selecting presentations, demos and posters in energy harvesting, storage, micro-power management and system integration based on real life applications. Thanks to the committee and our technical sponsors (IEEE PELS, ECPE, CONNECT and CPSS) an exciting program of presentations from industry and academia has been confirmed including Analog Devices, Carnegie Mellon, ST Micro, Ilika, ARM, UNIST (S. Korea), Fraunhofer, IMTEK-University of Freiburg, Tyndall, NCSU (North Carolina), Lightricity, Cap-XX, University of Southampton & United Technologies.

The workshop will demonstrate examples of successful energy harvesting products already created via synergies between the energy harvesting source and the load demand developers. A key workshop message and driver is that emerging technologies, if properly guided and integrated, will enable a dramatic penetration of energy harvesting solutions into a broader range of applications.

EnerHarv is targeted at a broad audience ranging from potential adopters of energy harvesting for IoT devices for specific applications (building management, medical technologies, assisted living, environmental, conditional monitoring of equipment, systems, power supplies) to industrial and academic developers of materials and devices (active and passive) to systems integrators and installers of IoT solutions.

EnerHarv will be hosted by Tyndall National Institute in Cork, Ireland, May 29-31, 2018.  Tyndall is one of Europe's leading industry-led IoT research centers and is an epicenter for energy harvesting research.

An opportunity not to be missed for anyone interested in 'powering the Internet of Things.'


Registration is still open with limited spaces. Please visit www.EnerHarv.com or contact Mike Hayes (General Chair, michael.hayes@tyndall.ie) or Brian Zahnstecher (Technical Chair, bz@powerrox.com) to learn more.

A Power Supply Can't Fix All EMC Woes, Yet Partnering with the Right Power Supply Experts Early Can

A bout 30 years ago I attended a key supplier conference for a very large OEM for which I was the FAE assigned to the account. One of the activities at this conference involved an exercise conducted by a consultant. The consultant split the attendees into small groups and gave them all the assignment of getting a house painted. The groups would need to determine all requirements and considerations associated with painting a house. But there was a catch: One half of the groups would do so while planning to paint the house themselves. But the other groups would outsource the task to a painter or painting company.

After 30 minutes or so we compared our lists. The teams which presented on painting the house ourselves had much shorter lists of requirements which were not overly demanding. For example, if we spilled some paint, "we would just wait till the grass or bushes regrew and cut the paint splattered part out". On the other hand, the groups that "outsourced" the painting had much stiffer requirements such as "if paint is spilled or gets on the bushes, the painter must re-sod and replace the bushes at the painter's expense, no questions asked."   

This exercise taught a simple lesson: if you do a job yourself the expectations will be a lot lower than if you outsource it.

Now, fast-forward to the present. For many companies in the electronics design and supply chain, the business has not changed much except that the margins everyone is making are much lower and the expectations are probably even higher. But does the lesson learned all those years ago still apply?   

Recently I was called by one of our customers who was failing EMC in the test lab. They were using one of our competitor's power supplies and we had been talking with them about using ours because of its superior value and performance. It was hard to ascertain if our pitch was falling on deaf ears or not.


Fig. 1. A product failing EMC testing. When this happened to one of my prospective customers,
they assumed that the power supply was at fault and tried swapping power supplies to no avail.

But now, with their product failing compliance testing, suddenly we were important to them as evidenced by them calling me after hours. The discussion went something like "does your power supply have lower EMC than the one I'm now using?" Of course they were talking about radiated EMC as I already had helped them with selecting a line filter, which was sufficient to make sure either power supply would pass conducted EMC. With their product in the test lab there was real urgency as—chah–ching, chah–ching—the money meter was running with the test lab charging them by the hour as the customer tried to get their product to pass EMC (Fig. 1). 

I mentioned that I was going to be in their area the very next week and I offered to work with them in the test lab. When I arrived at the designated time, this would-be customer showed me what they had done thus far. Their product was in an RF anechoic chamber like the one shown in Fig. 2. They took the covers off and showed me the product and power supply location. Our competitor's product was buried inside the device with little shielding or attention to wire dress or filtering. Meanwhile our power supply was on the bench with an IEC cord feeding it ac from an outlet and twisted pair wires connecting the power supply's outputs to the product's electrical connections.

As I surveyed the scene, they asked "if your power supply can't pass, can you recommend one that will?" Like a gambler playing a slot machine, they were more than happy to keep pulling the power supply "handle" in hopes a better power supply would pay off and make them a compliance winner.  They thought it's like picking resistors off a catalog distributor's website or something similar.

However, both power supplies were running and every test was failing. I knew from experience that neither power supply was probably having much of an effect. The rails in the product were 12 V and 24 V at about 1 kW total. 

With those voltages in mind, I advised the customer to go to the auto parts store and buy a couple of car batteries. They could then run shielded cables from the batteries into their product's chassis to power it, and re-run all the tests from the 12 and 24 V dc. Batteries after all, produce no EMI. So can we agree at that point power supplies would have nothing to do with the test? They agreed and set the test up.

As I expected, they failed radiated emissions again with very little change in the emission profile. Whoops! The customer realized it was the house they painted themselves, so what now? "Oh, we will just get the CE mark and ship it out to beta customers," they decided, bypassing the requirement for an EMC test lab certification. And the unspoken parting message to me was "when I need more free consulting work without actually using any of your products, we will call you again."

Besides confirming that the painting-the-house lesson still holds true, this story also has a moral: The power supply does not cause all radiated emissions problems in the end product. But the customer will call the power supply company anyway because it's easy to blame the problem on what they think is the noisiest part of the system.

What Did We Learn?
Several mistakes were made by the customer in the above story:
1. EMC was an afterthought—if they had called me earlier we would have had more options and fixed it properly.

2. The power supply selection, particularly the choice of the power supply vendor, was given as much consideration as the selection of paper towels and the power towel maker, for the towels used in the company restrooms. They thought the power supply was just another commodity item—it's all generic. So when a problem that might be power supply related occurred, they just kept trying anything and everything in the hopes that something would work. 

3. They waited until the end of the process to test the product for EMC with no pre-compliance testing.  

4. They didn't build a relationship with the power supply company or bother to select one that actually has field applications staff that can come and help. They waited until they had an emergency and when no support was available from the default supplier they asked us for help. Their alternatives would have been to suffer in silence or deal with phone support from a far off land.

5. They didn't design for EMC all during the design process from concept to finish.  

6. They thought that a power supply is always the main culprit in radiated emissions regardless of its integration in the end product with no consideration of their system impact or how the power supply is integrated in the system.

7. They kicked the compliance can down the road for later. CE won't accept other EMC approvals and other EMC agencies won't accept CE since all you have to do is pay a CE consultant to pass. This problem will surface another day. Probably when time to market is critical.

I offered to help the customer with a re-design of their product so they would pass EMC. I also mentioned that, in general, it's best to pick a power supply up front and then work closely with the supplier on the design of the product's I/O to the power supply, system design, filtering and such so that the test lab experience will be a good one. 

Power supply selection is much more important than most engineers realize. It's not just picking a part from the Internet. It's a system selection and partnership commitment. Beyond that, power electronics is a partnership relationship. It's a collaborative commitment to making sure your product passes all safety, compliance and regulatory testing on the first pass.

Power supplies for railway applications – On the rails to 2020

I n a study presented at the international rail exhibition, Innotrans 2016 in Berlin, the European Rail Industry summarized the state of the business as representing a market size estimated to reach 229 billion USD by 2020. This amount includes new infrastructures, trains and vehicles and an often hidden yet important part, railway modernization. From Asia to the USA, every country has a railway infrastructure, some of which some are 100 years old (e.g. catenaries).

To meet the growing market demand for enhanced safety and modernization in the USA the 'Grow America Act' supports railway modernization with predictable, dedicated investments. States and local communities need the certainty of sustained funding to make these transportation investments that are necessary to improve the infrastructure and support their economic growth. To meet this, the Act is investing $29 billion over a six year period to improve rail safety and invest in a National High-Performance Rail System. One particular area to benefit from the Act is Positive Train Control (PTC). PTC is a system of functional requirements for monitoring and controlling train movements, a type of train protection system. The Act also builds on current investments to enhance flexibility in financing programs that will better enable the rehabilitation of aging infrastructure. For sure, the power supplies share of these investments is marginal compared to heavy rolling stock or infrastructure. Though without power supplies, nothing would be possible, and so power designers are actively engaged in railway modernization.

As we approach the next edition of Innotrans, it is both relevant and interesting to take a minute to consider the many challenges that power supply manufacturers are facing in their quest to make railways safer, coupled with the highest service levels for passengers.


From conservative to progressive

For decades, the railway sector has been a challenging area for the power supply industry to develop very specific power solutions to meet the requirements of this complex market. The sector consists of three main categories: new equipment, modernization, and the maintenance and upgrading of equipment that entered service 10 years ago or more. Each of these categories represents particular demands on the part of the developer and requires skills specific to each case.

Although the railway sector is very conservative and priority is given to reliability and robustness, the new generation of "digital technology trained" engineers involved in the development of new rail systems are increasingly integrating digital control and encouraging the implementation of energy-efficient topologies such as the Gallium Nitride transistors. In the railway sector this approach is quite new, requiring more extensive qualification work during product development, bringing new constraints for engineers responsible for guaranteeing durable solutions for the next twenty years. This is a very interesting aspect for design engineers and a great opportunity to cooperate directly with the design offices of major railway customers.

From point-of-load to multi kilowatts - with compliance

The range of railway applications is very wide and consists of a large number of applications requiring simple proximity voltage regulators point-of-load (POL) to converters or inverters of several hundred kilowatts powering the motors of traction engines and other traction vehicles. In term of overall railway market, if we exclude the service part of the segment, rolling stock represents the majority of applications, followed by infrastructure and finally, track side and signaling. Each of these sub-segments has its own requirements that are specific to its environment. For example, converters for vehicle (e.g. locomotive) startup control, so called Low Battery Voltage Starter (LBVS) are connected to high voltage catenaries to deliver a low battery voltage, requiring very high insulation and high-level safety constraints. In addition, all on-board equipment must comply with general standards such as EN50155, which covers electronic equipment used in rolling stock (a standard that incorporates many other standards such as EN 50121-3-2 for electromagnetic compatibility). The railway field is highly standardized and each development begins with an analysis of the application case and related standards.



In addition to the traditional standards governing operating quality, operational parameters and safety, after more than 20 years of evaluation and its publication in 2013, this year the EN45545 standard (resistance and fire behavior) has become mandatory for all rolling stock. This standard aims to eliminate the risk of fire during a technical incident and all toxic fumes resulting from combustion of the product. For power supply manufacturers, this means selecting components that meet this standard and carrying out additional tests to ensure full compliance with the various chapters of EN45545.

Apart from the large number of standards, one of the specificities of the railway sector is the fact that many applications have very specific requirements in terms of housings and connectors, often resulting in products that are dedicated to a particular customer. While the trend is towards the standardization of card modules such as DC/DC converters, for more complex products such as locomotive starter converters or decentralized battery chargers, custom designed product remains the norm. This requires a development capacity geared towards these products and a high degree of flexibility in production. In fact, despite a growing market (+6% per year), the volumes of power supplies used in the railway sector remain modest compared to the millions of units consumed in the telecommunications sector, requiring the manufacturers, such as Powerbox, to adapt their production tools to specific demands.

Designing power for long life time

The majority of customers in the railway sector require a 30 years or more availability for some critical equipment. This means that during development this service life must be taken into account, as well as the possibility of the replacement of certain components such as electrolytic capacitors affected by aging during life time, must be considered during the design. Knowing that railway power supplies can be exposed to severe environmental effects such as temperature variations or shock and vibration during the life of the product, equipment manufacturers include "components refreshment and re-calibration" in their specifications. It is common to see products delivered more than 15 years ago return to the manufacturer for review and updating. This practice is very specific to the railway sector and has a strong influence on the way feeds are designed.

Indeed, a 30-year lifespan obliges design engineers to select components with a low risk of obsolescence but also to design the product for possible upgrade during its useful life. This adds a level of complexity but also limits the introduction of new technologies. As mentioned above, engineers in charge of the development of tomorrow's railway systems want to integrate new technologies, but the limited knowledge of their lifecycle and sustainability raises questions about the level of risk associated with their introduction. This is a topical issue that is being debated within the railway community which on the one hand wants to modernize its power supply systems to make them more energy-efficient and with better communications, and on the other hand to guarantee a risk-free sustainability.

Time to market challenges

Basically, the technologies used to develop railway power supplies are very similar to those used in other segments, and with years of experience, developers of the former have built up expertise enabling them to reduce development times. However, new standards and the introduction of new technologies will increase development time. Considering the wide range of power supplies used in railways, if we exclude so-called "standard" products such as modules for boards having a development cycle of about 14 months, more of customers' complex projects can easily reach 24 or even more months awaiting approval. This means working closely with OEMs who, aware of these delays and facing increasing price competition from Asia, are pushing for the development of blocks of functions that can be reused on multiple projects.


Because of the large and increasing demand pressure for modernization of rail systems, the design lead times have to be shortened, which means a different approach. In the case of rolling stock, this is rather complicated involving a number of specific aspects such as certifications. In the case of traffic control and signaling systems, the constraints are less stringent and it is possible to use power supplies such as those for DIN rail mounting that already exist. An energy subsystem such as ones provided by Powerbox's Battery Backup Unit (BBU) can be customized in less than three months to meet specific demands, including the addition of radio transmission telemetry systems. This is the type of modularity that OEMs are beginning to implement in rolling stock, but it will take time.

The impact of modernizing railway networks on power supplies has many aspects because it is not conceivable to stop the operation of the existing systems, nor to replace all existing infrastructure. For rolling stock, this often involves the addition of complementary technologies such as Wi-Fi for passenger comfort or on-board telemetry to increase safety. In this case, the power supplies are of a rather standard type and are often part of the installed system without any major change to rolling stock.

In the case of major modernization of a complete train (what is usually referred as "refurbishment") which consists of the revamping of one that has already endured a long life span, equipment manufacturers ask power supplies manufacturers to develop Fit, Form and Function (3F) alternatives. That is, a revised and updated power supplies but where the units' fit, form and function remain the same, thus reducing implementation delays and guaranteeing the durability of the host equipment for many years. The development of a 3F power supply is very close to a specific development, but by combining the expertise of engineers, the platforms available from manufacturers specialized in the field of railroads, and the reuse of the original case or chassis it makes possible to reduce development times spectacularly.

Most of the modernization of European rail networks is carried out at tracks and signaling systems level. Accordingly, equipment cabinets very often remain in place and installers ask for 3F solutions from the power supply manufacturers that can be installed in place of the old systems; a relatively simple process of "old equipment out, new equipment in". In the case of very old systems, the technique used is to install an industrial chassis in the cabinet to facilitate the installation of standardized racks, which subsequently reduces the time required for updating, such as adding additional radio-telemetry systems or connecting the cabinet to fiber optic systems.

The general trend in railway power supplies is to reduce development times by adopting standardized or semi-standardized sub-assemblies. This is the intention of equipment manufacturers and increasingly the adopted solution for systems close to the tracks or embedded applications using card converters or cassettes. However there will always remain very specific power supplies requiring on-demand solutions that will continue to call upon very specific skills.
