PSMA Magnetics Committee and IEEE PELS High Frequency Magnetics Workshop

Power Magnetics @ High Frequency
Date: Saturday March 16, 2019
APEC 2019 Anaheim, California

The PSMA Magnetics Committee and IEEE PELS will conduct the fourth "Power Magnetics @ High Frequency" workshop on Saturday, March 16, 2019, which is the day before and at the same venue as APEC 2019.

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

The workshop will consist of two technical lecture presentation sessions, an interactive technology demonstration presentation session and a wrap session regarding the positive trends in power magnetics. The two technical lecture presentation sessions will each be followed by a panel Q&A session and the technology demonstrations will also be available during the breakfast just prior to the opening session of the workshop and during the networking session following the workshop's formal presentation sessions.

The morning session on ac power losses will begin with a keynote presentation by Gerry Hurley of the National University of Ireland, Galway, that will provide a technical overview of both technical sessions on ac power losses and thermal management issues with power magnetics, with more detail for the topics of the morning session relative to ac power loss calculation, modelling and measurement issues. Topics planned to be covered by the individual technical presentations of the session include: impact of core size and material, measurement and characterization methods, and data presentation methods relevant to the electronic power community. Other topics of interest are still being identified. The morning session will be followed by a panel Q&A with the morning's presenters.

The lunch session will be an interactive technology presentation session during which the workshop attendees can visit and engage with the experts as they provide technical demonstrations of different topics associated with magnetics design, modelling and characterization. Some of the technical topics are as follows: emerging magnetic material, magnetic materials in the commercial marketplace, magnetic materials on the horizon, methods to predict and measure thermal performance of power magnetic components, methods to characterize near magnetic field performance of magnetic components, measurement methods for ac power loss, analysis and prediction of ac power losses in magnetic components, and fundamentals of small signal characterization of power magnetic components.

The afternoon session on thermal management of power magnetics will begin with a keynote presentation by Dr. Peter Wilson of the University of Bath, United Kingdom, that will provide a technical overview of the topics to be covered during the afternoon session as well as some recent trends in the simulation and analysis of thermal implications of various power loss mechanisms.  Topics planned to be covered by the individual technical presentations of the session include getting the heat out, impact of design on power losses and temperature rise, impact of temperature on technical performance of the power transformers and inductors and impact of package assembly techniques used for integration of physically small and physically large magnetic components in power systems. The session will be followed by a panel Q&A with the afternoon's presenters.

The workshop will conclude with a presentation by Alexander Gerfer of Wurth Elektronik regarding positive trends with power magnetics.

The registration fee for the workshop is $375 per participant, reduced to $275 for PSMA members and IEEE PELS members. On February 1, 2019, the registration fee will increase to $425 reduced to $325 for PSMA members and IEEE PELS members. Previous workshops have sold out, so early registration is encouraged. There will be a $25 surcharge for onsite registration, if seating is available. Breakfast and lunch will be provided as part of the workshop. Electronic copies of the technical lecture presentations and technology demonstration presentations will be made available to the workshop participants.
