Power Magnetics @ High Frequency
Saturday March 19 2022
Prior to APEC 2022
George R Brown Convention Center
Houston, Texas

he PSMA Magnetics Committee and IEEE PELS are planning to conduct the seventh "Power Magnetics @ High Frequency" workshop on Saturday, March 19, 2022, which is the day before and at the same venue as APEC 2022 in Houston, TX.

The 2022 Power Magnetics @ High Frequency workshop will mark the return to the "in-person" workshop format after the virtual format used for the past two workshops in 2020 and 2021. The relevance and interest in the Power Magnetic @ High Frequency workshop series has been validated by over one hundred registered workshop attendees each and for the panel Q&A sessions that ran overtime for both the 2020 and 2021 virtual workshops. The most recent 2021 Power Magnetics at High Frequency workshop was held as a virtual event on Wednesday June 2 and Thursday June 3.

Day one of the 2021 workshop focused on EMI Issues Caused and EMI Issues Solved by Magnetics. The morning session consisted of presentations by Balaji Narayanasamy of Tesla, Ammad Javed of Ernst Abbe University of Applied Science Jena, Stefanie Birkenbach of Wurth Elektronik, Mike Arasim of Fair-Rite Products. Jared Quenzer of Wurth Elektronik, JC Sun of Bs&T, Frank Puhane of Wurth Elektronik and Asif Imran Emon of Stoneybrook University. The second day of the workshop focused on Integrated Magnetics. The morning session consisted of presentations by Bryce Hesterman of Utah State University, John Gallagher of Pulse Electronics, Mike Kavion Ranjram of Massachusetts Institute of Technology, Chema Molina of Frenetic, Shuo Wang of Virginia Tech CPES, and John Noble of Magnetics. The afternoon session each day opened with a "Best of the Best" summary of the morning presentations by Alexander Gerfer of Wurth Elektronik, followed by a keynote presentation. "High Frequency 'side-effect' Mitigation in Power Electronics Converters: Modelling and Filtering Solutions" by Dr Fang Luo of Stoneybrook University on the first day and "High Efficiency and High Density 48V LLC Converters with Integrated Planar Magnetics for Data Center Applications" by Dr Qiang Li of Virginia Tech CPES on the second day. Each day concluded with a panel Q&A discussion with all of that day's presenters. You can read about the workshop from the perspective of an attendee in a separate article in this issue "PSMA Magnetics Workshop Explores AI, Core Loss and EMI."

The purpose and focus of the Power Magnetics @ High Frequency Workshop are to identify the latest improvements in magnetic materials, coil (winding) design, construction and fabrication, evaluation and characterization techniques and modelling and simulation tools. The objective is to target those power magnetics advancements that are deemed necessary by the participants to meet the technical expectations and requirements of new and emerging market applications to satisfy the ever higher operating frequencies and emerging topologies which are being driven by the continuous advances in circuits topologies and semi-conductor devices.

The target audiences for the 2022 Power Magnetics @ High Frequency workshop include the designers of power magnetic components for use in electronic power converters responsible to implement the most technologically advanced power magnetic components that are necessary to achieve higher power densities, specific physical aspect ratios such as low profile, higher power efficiencies and improved thermal performance. The target audiences also include people involved in the supply chain for the power magnetics industry ranging from manufacturers of magnetic materials and magnetic structures, fabricators of magnetic components, providers of modelling and simulation software as well as manufacturers of test and characterization equipment.

The 2022 Power Magnetics @ High Frequency will open with a keynote presentation by Charles Sullivan of Dartmouth University followed by several lecture presentations regarding the impact of magnetic core geometry and physical dimensions on magnetic component characteristics and specification parameters. In addition to the brief Q&A period after each individual presentation, there will be a panel of the presenters at the end of the session to address topics requiring more detail as deemed by the workshop attendees.

During lunch, breakfast, and the networking hour at the end of the workshop there will be an interactive session of tabletop technology demonstrations each addressing specific technical disciplines and capabilities consistent with the workshop agenda. Each technology demonstration station will include a ten-minute presentation at fifteen-minute intervals. Interaction between the attendees and the presenters is highly encouraged during this portion of the workshop as a segue from the opening keynote presentation and the technical issues session.

If anyone would like to participate as a presenter for the technical demonstration session, please contact the organizing committee by email to power@psma.com with a description of your proposed technical capabilities topic. We are limited to ten technology demonstration stations.

Based upon survey responses from the 2021 workshop, the afternoon session will focus on magnetics design for manufacturing, reliability, and safety agency requirements. A keynote presentation will be followed by a series of related technical presentations. In addition to the brief Q&A period after each individual presentation, there will be panel of the presenters to address topics requiring more detail as deemed by the workshop attendees. 

The specifics for the workshop structure and the presentations for the workshop are currently in progress. If anyone is interested in presenting on the impact of magnetic core geometry, physical dimensions, manufacturability, reliability and safety agency requirements on magnetic component design, characteristics, and parameters, please contact the organizing committee through by email to power@psma.com.

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/magnetics/workshop) over the coming months.
