PSMA Magnetics Committee and PELS TC2 High Frequency Magnetics Workshop
Power Magnetics @ High Frequency
Saturday March 18 2023
Prior to APEC 2023
Orange County Convention Center
Orlando, FL 32819

he PSMA Magnetics Committee and IEEE PELS are currently planning to conduct the eighth "Power Magnetics @ High Frequency" Workshop on Saturday, March 18, 2023, which is offered the day before and at the same venue as APEC 2023 in Orlando, FL. The purpose and focus of this 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 Workshop will target the advancements that are deemed necessary by the participants for power magnetics to meet the technical expectations and requirements of new market applications being driven by higher operating frequencies and emerging topologies together with continuous advances in circuits topologies and semi-conductor devices.

The 2023 workshop will build on the successful return to in-person of the 2022 Power Magnetics @ High Frequency Workshop that was held on Saturday March 19 in Houston, TX in conjunction with APEC 2022 - after two years of virtual workshops. The morning technical lecture session of Saturday June 19 focused on Effects of Core Geometries on Magnetic Characteristics with presentations by Charles Sullivan and Thomas Guillod, Dartmouth College; Juan Aguarón, Frenetic; Rico Wach, TRIDELTA Weichferrite; JC Sun, Bs&T; and Alex Hanson, University of Texas – Austin. The afternoon technical lecture session focused on Magnetics Design for Manufacturability, Reliability and Safety with presentations by George Slama, Wurth Elektronik; Vladimir Alexiev, Power Integrations; Matt Dvorak, BH Electronics; and Dennis Feucht of Innovatia Laboratories. Student poster presentations by Ping Wang, Princeton; Diego Serrano, Princeton; Michael Solomentsev, University of Texas; and Moien Mohamadi,University of Illinois at Chicago were available during the breakfast and lunch sessions. Technology demonstrations by Chema Molina, Frenetic; JC Sun, Bs&T; Arturo Mediano, University of Zaragoza; Dheeraj Jain, Wurth Elektronik; Brad Yourish, Magnetics; James Lau, Coil Winding Specialists; Adrija Stupar and Tom Wilson, SIMPLIS Technologies; Mark Rine, Hitachi Metals; and Mike Arasim, Fair-Rite were available during the breakfast and lunch sessions. The technical program closed with a summary overview "Best of the Best" by Alexander Gerfer of Wurth Elektronik of the technical presentations, poster presentations and technology demonstrations. Alex Hanson, Mike Arasim and Chema Molina represented the Magnetics Workshop during the joint Capacitors and Magnetics Rap Session during the networking hour to close out the workshop.

The target audiences for the 2023 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 theme of the 2023 Power Magnetics @ High Frequency will be magnetic component design across applications ranging from milliwatts to megawatts. The workshop will address applications areas such as IoT, servers, integrated voltage regulators (IVR), transportation electrification, wireless charging for mobile and electric vehicles and solid-state transformers. The workshop will also include presentation and demonstrations to address specific technical issues relative to high voltage and high current design such as corona, insulation, encapsulation, etc., that were identified in the post workshop survey for the 2022 workshop. As with past workshops, the morning and afternoon sessions will open with keynote presentations that cover a wider range of topics and issues followed by lecture presentations on specific application areas or technical issues. In addition to the brief Q&A period after each individual lecture presentation there will be a panel of the presenters at the end of the session who will address topics requiring more detail as deemed by the workshop attendees.

During breakfast, lunch 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 agenda as a segue from the opening keynote presentation and the technical issues session.

If you would like to participate as a presenter for the technical demonstration session, please contact the organizing committee through PSMA via e-mail to power@psma.com with a description of your proposed technical capabilities topic. We are limited to no more than ten technology demonstration stations.

The specifics for the workshop structure and the presentations are currently in progress and are not finalized. If you are interested in being considered as a presenter  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 PSMA via e-mail to power@psma.com .

The successful return of the 2022 workshop to the in-person format provides the enthusiasm and momentum for a successful 2023 workshop. More details regarding the agenda for the 2023 Power Magnetics @ High Frequency 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.
