Workshop

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

Saturday March 18 2023
Prior to APEC 2023
Orange County Convention Center
Orlando, Florida

Capacitors have a major impact on your design. Attend this workshop to learn more about selecting the correct capacitors to help to improve design performance.

The PSMA Capacitor Committee is delighted to announce the 6th Annual Pre-APEC Capacitor Workshop sponsored by PSMA and IEEE PELS to be held on Saturday, March 18, 2023, which is the day before and at the same venue as APEC 2023 in Orlando, FL.

The 2023 workshop will continue the focus on the latest Capacitor technologies and applications to educate and to inform the industry about recent developments in the Capacitor Industry. Each year interest in the workshop grows and the valuable feedback from attendees is used for planning the next event. The first workshop, in 2018, introduced the basics, and the subsequent workshops have each gone into more details on the technologies and materials. For 2023, the workshop will focus on a question a lot of engineers ask themselves, "What is the impact of the capacitor in my design and how can the right capacitor help me to achieve proper compliance?"

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 have a good understanding of capacitor issues. The PSMA Capacitor Committee is committed to educate and share the most recent information available to meet the industry's needs.

In 2023, our aim is to deliver value to everyone who is working with capacitors, from newbies to advanced designers of DC-DC converters, frequency drives, inverters, and other power conversation applications. Everyone working in the industry faces the same questions when it comes to capacitors. Maybe this situation sounds familiar: The application works as expected in the lab setting, but when it is installed and is operating 24/7 issues arise. Now the question is why? The workshop agenda will include presentations from a range of manufacturers, designers, and testing companies, as well as researchers from leading universities, to help you answer this question and avoid problems in the future.
Topics for the 2023 workshop include:

  • Why products fail the EMC test and how capacitors can help to pass it,
  • How can design efficiency be increased through proper capacitor selection,
  • The impact of capacitors on sustainability,
  • How an understanding of capacitor technology can help to recognize potential application issues,
  • Overview of current and emerging capacitor technologies and their specific behaviors.

The organizers aim is to provide an optimal balance between practical content delivered by leading capacitor manufacturers and a view of technology advances offered by worldwide renowned universities. The agenda will include keynote presentations from recognized experts and technical presentations on ongoing advances in capacitor research and development. The workshop will also feature panel discussions with the presenters to address questions from attendees and to expand on the materials they presented. During breakfast, lunch and the end-of-day networking period there will be demonstrations of products, technologies, equipment, and measurements to highlight many of the key concepts discussed during the presentations.

The full details of the workshop structure and the presentations are currently in progress. Please contact Frank Puhane (Frank.Puhane@we-online.de) of the Organizing Committee if you have any specific areas or issues you would like to see addressed at the workshop or if you are interested in being considered as a workshop presenter.

The latest information on the agenda as well as registration information of the workshop will become available on this page over the coming months.

"How Materials and Environmental Effects Influence Capacitor Performance"

The PSMA Capacitor Committee and IEEE PELS held the fifth annual pre-APEC Capacitor Workshop "How Materials and Environmental Effects Influence Capacitor Performance" on Saturday March 19, 2022 at the George R. Brown Convention Center in Houston, TX. The workshop participants and presenters from around the world came together for the program which included 14 presentations and 4 demonstration tables where experts showed many applications and measurement methods. The 2022 Workshop was successful and notable in that we were finally able to meet our customers, colleagues and friends in-person again after holding virtual workshops in 2020 and 2021.

After breakfast in the Demonstration Area, the Workshop began with a keynote presentation "The Next Decade Capacitor Requirements" from Tomas Zednicek, President of EPCI - European Passive Components Institute, who discussed the future of capacitor technologies with a special focus on materials, reliability and sustainability. This was followed by a presentation by William Greenbank from Centre for Industrial Electronics (CIE), University of Southern Denmark, who provided insight into the latest academic research on capacitor materials for the green transition. Frank Puhane, Würth Elektronik, rounded out the first session with a summary of the differences for Class 1/Class 2 MLCCs with a special look at the terminations.

The second session focused on Electrolyte and Tantalum Capacitors. Stephan Menzel from CapXon showed aluminum e-cap solutions for applications with demanding environmental conditions including increased operating temperatures or vibrations where designing a power supply requires a bulk capacitor to ensure good performance. Daniel West from Kyocera-AVX presented an overview of different options and trends to select the right bulk capacitor with a focus on reliability. When the application requires the highest possible volume capacitance, the solution favors tantalum capacitors, and it was a great honor to have Philip Lessner, CTO of KEMET, to guide us through the world of tantalum capacitors. In the final presentation of the morning, Nihal Kularatna from the University of Waikato explained how Supercapacitors could be used for renewable energy and DC micro grid applications. The session concluded with a panel discussion including many of the morning's presenters.

After this wealth of information, it was time for a joint lunch with attendees from the concurrent Power Magnetics @ High Frequency Workshop in the demonstration area. Workshop participants were able to visit the demonstrations from both workshops, discuss the morning program with the presenters and other workshop attendees, and to network with friends and colleagues.

Building on the technologies, trends and selection procedures that had been reviewed in the morning sessions, the first afternoon session focused on the influences of environmental conditions on capacitor applications. This session included not only how temperature and humidity affect capacitors performance, but also the impact of other influences such as the AC voltage and the packaging.  Frank Puhane showed how the different capacitor technologies behave under temperature influences and Philip Lessner explained how capacitors behave in a high humidity environment. Since the characteristics of MLCCs will change not only through DC bias, but also through AC bias, the session concluded with presentations by two well-known experts on capacitors presenting on this topic. John Bultitude from KEMET gave us insight into the MLCC rating for AC Applications and Douglas C. Hopkins from North Carolina State University then went on to discuss packaging for higher AC voltages and future trends in high power converters.

The final technical presentation session focused on the measurement and characterization of capacitors. Measurement and characterization should always be considered together since how the capacitors are measured is crucial for making comparisons. Therefore, Jon Izkue Rodriguez from Würth Elektronik showed how to interpret data sheets and how different components are measured. This topic was further demonstrated in a related demonstration station. High power converters, as described by Douglas C. Hopkins, use DC link capacitors which should have a very low parasitic inductance (ESL). Measuring the ESL can be a challenge and Ronald Alexander from Zurich Instruments presented on how to accomplish this. The final presentation, provided by Marcus Sonst from Rohde & Schwarz, was on how to determine the aging in an AC/DC flyback application using an oscilloscope.

The information-packed day concluded with a joint Capacitor and Magnetics Rap Session moderated by Alexander Gerfer, CTO of Würth Elektronik. The panel members Douglas Hopkins, Philip Lessner and Tomas Zedineck representing Capacitors and Mike Arasim, Fair Rite Products Corporation; Alex Hanson,University of Texas at Austin; and Chema Molina, Frenetic representing Magnetics had very interesting and exciting discussions on the topic of selection, sustainability and applications of passive components.
