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

he PSMA Magnetics Committee together with IEEE PELS will hold the seventh "Power Magnetics @ High Frequency" Workshop as an in-person event on Saturday, March 19, 2022 -  the day before and in the same venue as APEC 2022 at the George R. Brown Convention Center, Houston, Texas.

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 focus is to target the advancements deemed necessary by the presenters and the workshop participants for power magnetics to meet the technical expectations and requirements of new market applications for higher operating frequencies and emerging topologies driven by continuous advances in circuits topologies and semiconductor 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 individuals 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 morning technical session will feature a keynote presentation and four lecture style presentations with a five-minute Q&A after each lecture presentation followed by a Panel Discussion. The schedule for this session is:

• Keynote: "Magnetic Core Geometry Influences on Component Performance," Charles Sullivan, Thomas Guillod, Dartmouth College
• "Geometry Effects on Magnetic Core Losses," Juan Aguarón, Frenetic
• Panel discussion on core geometric factors impacting magnetic core and component parameters led by Charles Sullivan and Juan Aguarón. Everyone's participation is encouraged.
• "Uncertainties of Ferrite Parameters," Rico Wachs, TRIDELTA Weichferrite, and JC Sun, Bs&T
• "Where does Current Actually Flow in High-Frequency Magnetic Components?"Alex Hanson University of Texas, Austin
• Panel discussion on the impact of magnetic geometries on magnetic core and component parameters with Charles Sullivan, Juan Aguarón, Rico Wachs, JC Sun and Alex Hanson. Everyone's participation is encouraged.

During breakfast and lunch there will be a joint interactive session available with tabletop technology demonstrations covering both Magnetics and Capacitor technologies that will address specific technical disciplines and capabilities consistent with each workshop's agenda. The attendees are encouraged to interact with the presenters during this time as a segue to enhance and expand the technical presentation sessions.

The Magnetics technical capabilities and disciplines that will be demonstrated and displayed during the technology demonstration/poster session are as follows:

• Technology Demonstrations
• "Real Time Magnetics Design Using Artificial Intelligence," Juan Aguarón, Frenetic
• "Loss vs. E/U Shaped Cores," JC Sun, Bs&T
• "Near Field Probes for Measurements and Characterization of Near Magnetic Fields," Arturo Mediano, HF Magic Lab University of Zaragoza
• "Selecting Inductors and Capacitors for EMI Filter Design," Dheeraj Jain, Wurth Elektronik
• "Manufacturing of Unique Winding Geometries," James Lau, Coil Winding Specialists
• "Enabling Concurrent Design of Electric and Magnetic Circuits using the SIMPLIS Magnetics Design Module," Tom Wilson, Andrija Stupar, SIMPLIS Technologies
• "Emerging Magnetic Materials and Magnetic Structures," Chuck Wild, Dexter Magnetics
• Hitachi: Mark Rine
• Fair-Rite: Mike Arasim
• Magnetics: Brad Yourish
• Posters
• "Matrix Coupled All-in-One Magnetics for PWM Power Conversion," Ping Wang, Princeton University
• "Magnet, Large Database for Core Loss Machine Learning," Diego Serrano, Princeton University
• "Rapid High-Frequency Transformer Simulation and Optimization," Michael Solomentsev, University of Texas Austin
• "Integrated Magnetics Geometries in EV Fast Chargers," Moien Mohamadi, University of Illinois at Chicago

The afternoon technical session will feature a keynote presentation and three lecture style presentations, each followed by a five-minute Q&A. The session will conclude with a twenty-minute panel Q&A The schedule for this session is as follows:

• Keynote: "The Journey to Reliable Magnetics," George Slama, Wurth Elektronik
• "Planar Magnetics for Auxiliary Power Supplies," Vladimir Alexiev, Power Integrations,
• "Considerations for Reliable Magnetics, A non-exhaustive reference," Matt Dvorak, BH Electronics
• "Optimization of Power Magnetic Design," Dennis Feucht, Innovatia Laboratories
• Panel Discussion with George Slama, Vladimir Alexiev, Matt Dvorak, and Dennis Feucht will address topics of interest relative to reliability, manufacturing, and safety.  Everyone's participation is encouraged.

The technical sessions of the workshop will close with remarks by Alexander Gerfer of Wurth Elektronik summarizing the Best of the Best from the magnetics program and their impact on the evolution of power magnetics positively contributing to the power electronics industry.

The 5th Annual 2022 PSMA/PELS Capacitor Workshop, "How Materials and Environmental Effects Influence Capacitor Performance," will be held concurrently with the Power Magnetics @ High Frequency Workshop. Continuing the tradition from previous years, the workshops will share the demonstration area.

New this year will be a joint Magnetics and Capacitors Rap Session addressing the trade-offs between choice of magnetic components and capacitors. This Rap Session will be held during the networking reception after the afternoon technical presentation sessions have been completed. Workshop attendees are encouraged to submit questions to the panel of magnetics and capacitor experts during the Rap Session.
