Design Techniques for the 21st Century – Behind the Scenes, Make Sure You Choose & Use the Correct Capacitor

PSMA and IEEE PELS Sponsor 2021 Capacitors in Power Electronics Workshop in conjunction with APEC 2021

Virtual workshop will be held on June 29-30, 2021

The PSMA Capacitor Committee is excited to announce the 2021 Capacitor Workshop sponsored by PSMA and IEEE PELS. We continue our efforts to educate and inform the industry about the latest news and developments of the Capacitor business, which is reflected by the fact that 2/3 of passive components are caps. The 2021 Capacitor Workshop will be the fourth in the series. Each year we are happy to see a growing interest and receive valuable feedback from our attendees that directs us as we plan our next events. The 2021 Capacitor Workshop is going to open new doors: put a light onto interesting and trending topics around capacitors, their technologies and various applications.

The PSMA Capacitor Workshop Organizing Committee has a clear mission:

The PSMA Capacitor Committee Annual Workshop aligned with APEC has a mission to educate the attendees on capacitor trends, technologies, and innovations. Wherever and whenever applications need energy, Capacitors are at the spotlight, and as energy moves the world it is incumbent for everyone to keep their finger on the pulse of capacitor issues. We are committed to present the best information available to meet the industry's needs.

Along with so many of us, the Capacitor Workshop Committee learned a lot through the process of changing the traditional format of a face-to-face workshop at previous APEC events into a virtual workshop in 2020. For 2021 we are preparing for three possibilities: 100% live and on site, 100% virtual and a hybrid. Planning for these different options is part of our strategy to ensure that the 2021 workshop meets the needs of the attendees and is a success.

Are you interested in learning more about the high temperature capabilities of EDLC Super-Capacitors, high voltage hybrid Aluminum Polymers?  Have you asked yourself, what is the difference between the result of the simulation you did and the first measurements of your prototypes? How a capacitors' lifetime will differ when environmental conditions are changing? All those and many more questions are targeted to be answered in Phoenix. In fact, the 2021 workshop headline is: "Design Techniques for the 21st Century - Behind the Scenes, Make Sure You Choose & Use the Correct Capacitor".

The 2021 Capacitor Workshop will offer value to everyone, from students and new engineers to advanced designers of DC-DC converters, frequency drives, inverters, and other power conversation applications. Multiple topics from industry, automotive and other application areas are included the agenda of this workshop. We look forward to providing information and answers to more and more Capacitor questions at the 2021 workshop.

The Capacitor Workshop has always been planned in parallel with the Power Magnetics @ High Frequency Workshop, with attendees having the opportunity to visit the demonstration stations for both workshops. However, in 2021 we go even one-step further, bringing together – Magnetics & Capacitors. With a joint demonstration station of magnetics and capacitor specialists, we will demonstrate how to design a best-in-class filter.

By combining theoretical content and practical lectures with topic related interactive demonstration stations, attendees get a full view of the technology from concept to practical implementation. The workshop agenda will address application-based challenges on capacitor technologies, the latest capacitor developments as well as the impact of market shortages on new developments and possible solutions to overcome actual problems.

The 2021 Capacitor Workshop will cover the following topics:

  • Automotive & eMobility
  • Design of
    • Power Supplies
    • Filters
    • Drives
  • Environmental influences on various capacitor technologies
  • Difference between simulation and reality

The organizers aim is to provide an optimal balance between theoretical and practical information. The presenters are from leading capacitor manufacturers and representatives from worldwide renowned universities. There will also be presentations on ongoing advances in   capacitor research and development. There will be keynote presentations from forward-thinking market players. In addition, there will be panel sessions of the presenters to address questions and expand on the materials they presented.

The workshop will include interactive demonstration sessions to highlight many of the key concepts discussed during the presentations. These demonstration stations will be available during the breakfast prior to the opening session, lunch, and the networking session at the end of the day's events, giving attendees the opportunity to meet the presenters and professionals directly and get in-touch with the various technologies and their advantages.

The formal presentations are designed to open new horizons of capacitor technologies to attendees and to address questions engineers have, or will have, when working with different capacitor dielectrics. If you have any specific areas or issues that you would like included, please email Pierre Lohrber of the Workshop Organizing Committee at

The early registration fee for the workshop is $225 per participant reducing to $165 for students and members of PSMA and IEEE PELS. On May 1, the registration fee will increase to $255, reduced to $195 for students and members.

Registration includes attendance at the live workshop sessions as well as access to all of the workshop materials and session recordings.  Attendees of the “Design Techniques for the 21st Century – Behind the Scenes, Make Sure You Choose & Use the Correct Capacitor” workshop will also be able to attend the “Power Magnetics @ High Frequency” workshop at no additional cost. 

Student fee waivers made possible with the generous support of workshop partner Cornell Dubilier, will be available to up to three students to attend the workshop. Interested students can apply for a waiver at The application deadline is Friday April 23.

We look forward to your participation.

More information, including the detailed workshop agenda, will be available on this webpage in the coming weeks.

How to Choose and Define Capacitor Usage for Various Applications, Wideband Trends and New Technologies

PSMA and IEEE PELS Sponsored Workshop Webinar Series Tuesdays April 21 – May 5, 2020

The Power Sources Manufacturers Association (PSMA) and the IEEE Power Electronics Society (IEEE PELS) jointly sponsored the virtual capacitor workshop "How to Choose and Define Capacitor Usage for Various Applications, Wideband Trends, and New Technologies". The Capacitor Workshop had been scheduled in parallel with a Magnetics Workshop on the Saturday prior to APEC.

The year 2020 started with a major challenge that hit all of us hard. After months of preparation for the third consecutive PSMA and PELS Capacitor Workshop scheduled on March 14th in New Orleans everything changed dramatically. With a worldwide travel ban and the cancellation of APEC, we had to change the very successful in-person workshop format into a virtual session in just a couple of weeks. Despite the difficulties the Workshop Committee faced, their primary goal was to create the highest possible value to all of the registered attendees which would closely follow the agenda planned for the in-person workshop. Both of the committees, Magnetics and Capacitor agreed, that as an additional bonus, registered attendees would be offered both workshops regardless of which workshop they had originally signed up for.

With the tremendous effort of the Capacitor Committee and the magnificent support of the PSMA staff, the virtual workshop outline solidified and the schedule was published accordingly.  On three consecutive Tuesdays, that started on April 21st the Capacitor Workshop attracted presenters and attendees from around the world. A mixture of technical based presentations from industry professionals and contributions from professors of international renowned universities were well fitted into the three sessions. Supporting demonstrations as well as a live video panel discussion took place to make this virtual workshop a success.

Without exaggeration, the 2020 virtual Capacitor Workshop was a success based on the outstanding efforts of all presenters. With professors and technicians, technical marketing experts and specialists covering a wide range of subjects the value to all attendees was much more than just a replacement of the planned workshop in New Orleans. Brilliant sessions, presented by international speakers from the United States to Europe down to New Zealand had been a promise to all of the participants. Each session concluded with a live and interactive question and answer session and panel discussion that continued until all audience questions were addressed. The feedback was more than just positive. We are pleased to recap that, despite the unique circumstances, the 2020 Capacitor Workshop fulfilled the mission of the workshop organizing committee "to educate the attendees on capacitor trends, technologies, and innovations… to present the best material available to meet the industry's needs." All of the highest praise, and respect is extended to the presenters, the PSMA and IEEE PELS staff and all of the attendees for their contributions. All of the presentations were made available to participants and each session was recorded and is available to all registrants for viewing on demand.

The 2020 Capacitor Workshop was different in many ways to prior years. With the feedback provided by attendees following each session, we learned a lot about this format and were able to incorporate many of suggestions received in the later sessions. While nothing will fully replace the face to face dialog and interaction during an in-person workshop, the virtual session is an excellent alternative and/or add-on to increase the value and convenience to attract more attendees all over the world. And the virtual format also allowed individuals to participate in both the Capacitor and Magnetics workshops. With these and additional takeaways from the workshops in 2020 and previous years, we are looking forward to an even brighter future and even more successful workshop 2021 in Phoenix AZ, or perhaps virtually again.
