Power Magnetics @ High Frequency
Saturday March 15 2025
Prior to APEC 2025
Georgia World Congress Center
Atlanta, GA 30313

he PSMA Magnetics Committee and IEEE PELS is currently planning to conduct the tenth Power Magnetics at High Frequency Workshop on Saturday, March 15, 2025, which is the day before and at the same venue as APEC 2025 in Atlanta, GA. The 2025 workshop builds on the ongoing dialogue of the workshop series over the past nine workshops.

The purpose and focus of the workshop are to show the latest improvements in magnetic materials, coil (winding) design, construction, fabrication, evaluation, characterization techniques, modeling, and simulation tools. This is to target the advancements considered necessary by the participants for power magnetics to meet the technical expectations and requirements of new market applications for higher operating frequencies and emerging topologies that are driven by continuous advances in circuits topologies and semi-conductor devices.

The target audiences for the 2025 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 audience also includes 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 measurement equipment.

The theme of the 2025 Power Magnetics @ High Frequency workshop will be integrated magnetics, defined as magnetic structures that perform two or more functions. The workshop will address various aspects of integration for both lateral and vertical power delivery. The planned topics include various levels of integration ranging from magnetic components co-packaged with silicon in Power System in Package (PSiP) devices, magnetics embedded in substrates, fabricating magnetics as part of the semiconductor wafer process and traditional core structures used in unique ways. The workshop will also cover integration of magnetic functions for new circuit topologies including coupled inductors, LLC, TLVR and VIRT.

The morning and afternoon sessions will open with keynote presentations that provide an overview of the advancements over the past ten years relative to new structures, new materials, and improved modelling techniques to validate designs for more complex technical specifications. Technical specifications for integrated magnetics include electrical, multiple functionalities, packaging, and thermal requirements.

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 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 part of the agenda.

If anyone 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 topic. The workshop is limited to ten technology demonstration stations.

There are opportunities for organizations to support the workshop as partners. Please contact the organizing committee through PSMA via e-mail at power@psma.com to obtain more details on partner opportunities.

More details about 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.
