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

he PSMA Magnetics Committee and IEEE PELS will conduct the tenth "Power Magnetics @ 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 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 deemed necessary for power magnetics to meet the technical expectations and requirements of new and evolving market applications. These are driven by higher operating frequencies and emerging topologies together with continuous advances in circuits topologies and semiconductor 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, those who are responsible to implement the most technologically advanced power magnetic components 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 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 will be integrated magnetics, defined as magnetic structures that perform two or more functions.

The workshop will open with a keynote presentation by Minjie Chen of Princeton providing an overview of advances in the physical structures and fabrication of magnetic devices for power applications over the past ten years. The morning session will consist of lecture presentations by Ranajit Sai of Tyndall discussing trends of magnetic designs for 2.5D and 3D packaging. Jens Kehl of Wurth Elektronik will address advances in inductive components fabricated on 300 mm silicon substrate wafers, Sebastian Bachman of Tridelta Weichferrite will address industry transitions relative to processing and shaping magnetic cores and John Mcdonal of Atlas magnetics will discuss a new generation of magnetics for improving performance of Power Supply in Package (PSiP) devices.

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. Workshop attendees typically spend ten to fifteen minutes at each technology demonstration station viewing informal interactive presentations. The technology demonstration format facilitates Interaction between the attendees and the presenters as a segue from the morning technical presentation sessions to the afternoon lecture presentation session. Technology demonstrations are confirmed by JC Sun of Bs&T, Akihiko Saito of Daido Steel, Kosuke Yuasa of Daido Steel, Mike Arasim of Fair Rite, Wilmar Martinez of KU Leuven, Lukas Mueller of Micrometals, Alfonso Martinez of Open Magnetics, Kevin Hermanns of PE Systems, Andres Arias and Risha Yu of Premier Magnetics, Jun Wang of the University of Bristol and Efran Bernal of Wurth Elektronik. We still have room for additional technology demonstrations. If anyone is interested to present a technology demonstration, we encourage them to contact the workshop organizing committee via e-mail to power@psma.com.

The afternoon session will begin with a keynote presentation by Charles Sullivan of Dartmouth addressing trends of electrical requirements, modelling and simulation of magnetic components over the past ten years. The keynote presentation will be followed by lecture presentations by Mike Ranjram of Arizona State University addressing recent advances of Variable-Inverter-Rectifier-Transformer (VIRT) hybrid electronics, Alfonso Martinez of Wurth Elektronik addressing simulation techniques for integrated magnetic functions and Michael Freitag of Yageo addressing the impact of using nanocrystalline powder core material on the design of inductors for TLVR applications.
