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

PSMA and IEEE PELS Sponsor 2021 Pre-APEC Capacitors in Power Electronics Workshop

The Power Sources Manufacturers Association (PSMA) and the IEEE Power Electronics Society (IEEE PELS) will jointly sponsor a capacitor workshop titled "Design Techniques for the 21st Century – Behind the Scenes Make Sure You Use the Correct Capacitor." This Capacitor Workshop is being planned as an in-person event in parallel with a Magnetics Workshop on the Saturday prior to APEC. Given the unknowns surrounding the future of the Pandemic and travel restrictions, we are structuring the event in such a manner that we will be able to easily transition the in-person workshop to a virtual event. For those of you that were part of the 2020 virtual workshop, you know how enormously successful this event was. The Workshop was broken into three Webinars with open discussions and demonstrations included. The presenters originally scheduled for the in-person workshop presented at the online sessions and ensured that every question was answered. Anyone who registered was invited to attend both the Capacitor and MagneticsWorkshops and has access on the PSMA website to all of the workshop presentations and webinar recordings.

The 2021 Capacitor Workshop will be the 4th of its kind and we are excited to bring to you once again a robust mix of new technology, research, design trends, evolving applications and much more. With the growing interest and excellent feedback from former attendees, we know that the past workshops have provided valuable information and insights to attendees and also which areas of Capacitor technology to focus on in the future. The upcoming workshop will do just that: highlight interesting and trending topics in the use of capacitors, current and future technologies, with a focus on trending applications. At this time, we are pleased to announce an incredible mix of professionals from industry leading capacitor manufacturers including KEMET, CDE, TDK & Wurth Electronics as well as experts from universities around the world. As a brief outline, below are some of the primary subjects that we will be including in the 2021 workshop:

  • DC Link Focus – Pros and Cons of using different capacitor types focusing on reliability, voltage limits, and more
  • Evolving New Technology – High Voltage Polymers, High Temp Supercaps, Ceramics, and more
  • Characterization of Capacitors – Simulation Tools, Comparing simulation to reality, and more
  • Environmental Influences – Behavior of caps under various extreme conditions: Temperature, Pressure, Humidity, Mechanical Load, and more
  • Measurements – Interpretation of datasheets, measuring electric cap values, and more

In 2021 we will also continue the very successful and highly appreciated interactive session of tabletop technology demonstrations. 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. Meet the presenters and professionals directly and get in-touch with the various technologies and their advantages. The demonstrations from both the Capacitor Workshop and the Power Magnetics @ High Frequency Workshop that is scheduled in parallel will be in the same room, allowing attendees of both workshops to benefit from all of the displays.

We look forward to your participation. More details regarding the agenda for the workshop as well as registration for the workshop will become available on the PSMA website (www.psma.com/technical-forums/capacitor/workshop) over the coming months.

If you have any questions or anything specific that you would like us to cover please email the workshop organizing committee at power@psma.com.

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.
