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 first nine workshops.

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. This is to target the advancements deemed 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 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 2025 Power Magnetics @ High Frequency workshop will be integrated magnetics. The workshop will address various aspects of integration for both lateral and vertical power delivery. The various levels of integration from integrating magnetic components with silicon in packaged devices, embedding magnetics in substrates and fabricating magnetics as part of the semiconductor wafer process are planned topics. The workshop will also cover integration of magnetic functions for new circuit topologies including coupled inductors, LLC and TLVR. 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 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 agenda 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 through PSMA via e-mail to power@psma.com with a description of your proposed technical capabilities topic. We are limited to ten technology demonstration sessions.

The specifics for the workshop structure and the presentations for the workshop are currently in progress and are not finalized. 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 PSMA via e-mail 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.

The 2024 Power Magnetics at High frequency Workshop was held on Saturday February 24 in Long Beach California. The 2024 workshop marked the return of the workshop to location of the inaugural workshop in 2016.

The morning technical lecture session focused on opportunities for new magnetic designs for emerging applications. The morning session consisted of presentations by Johan Kolar and Jannik Schafer of ETH Zentrum, Jonas Muehlethaler of Frenetic, Qiang Li of CPES, Lukas Mueller of Micrometals and David Zawacki of Cornell Dubilier.

The afternoon technical lecture session addressed special design issues such as thermal, dielectric and insulation design for different applications. The afternoon session consisted of presentations by Charles Sullivan of Dartmouth, Roman Jamy of Yageo, Zhicheng Guo of Arizona State University and Subhashish Bhattacharya of North Carolina University.

Student poster presentations by Adhistira Naradhipa of CPES, Daifei Zhang of ETHZ, Shubham Rawat of North Carolina State University and Shubham Dhiman of North Carolina State University, Hoaran Li of Princeton and Shukai Wang of Princeton were available during the breakfast and lunch sessions.

Technology demonstrations by JC Sun of Bs&T, Bharadwaj Reddy Andapally of CBMM, Mike Arasim of Fair Rite, Arturo Mediano of HF Magic Labs, Ryu Nagahama of Iwatsu, Lukas Mueller of Micrometals, Chuck Wild of Miles Platt, Andrija Stupar of Simplis Technologies, Slobodan Cuk of Teslaco, Juris Vencels of Trafolo and Jon Izuke Rodriguez of Wurth Elektronik were available during the breakfast and lunch sessions. The technical program closed with a summary overview "Best of the Best" challenging the magnetics industry to continue its history of innovations and quality improvements to address new markets by Alex Gerfer of Wurth Elektronik.

The dynamics of the 2024 workshop provides the enthusiasm and momentum for a successful 2025 workshop.
