The PSMA Magnetics Committee and IEEE PELS will hold the second workshop “Power Magnetics @ High Frequency – Transforming the Black Magic to Engineering” on Saturday, March 25, 2017 - the day before and in the same venue as APEC 2017 at the Tampa Convention Center in Tampa, FL. The successful inaugural workshop, “Power Magnetics @ High Frequency – Solving the Black Magic!”, was held in Long Beach, CA prior to APEC 2016.

The target audience for this workshop are professionals who are working to achieve higher power densities, low profile aspect ratio, higher efficiencies, and improved thermal performance in power products.

The workshop content is especially suitable for:
designers of power magnetic components
manufacturers of magnetic materials and magnetic structures
fabricators of magnetic components
providers of modelling and simulation software
manufacturers of test and characterization equipment

Workshop attendees are invited to arrive in the meeting room between 7:00 AM to 8:00 AM for a buffet style breakfast and informal discussions with their colleagues and peers. During the breakfast period, there will be an opportunity to preview the technology demonstrations which are part of the technical program.

There will be five (5) technical sessions.
The first opening technical session of the morning will feature two lecture style presentations. Each presenter will speak for thirty minutes followed by ten minutes for Q&A. The tentative schedule for this session is:
• Dr. Johann Kolar, ETH, “Impact of Magnetics on Power Electronics Converter Performance – State of the Art and Future Prospects”
• Donna Kepcia, Magnetics, “Smaller-Faster-Lower Cost—Magnetic Materials Meet Rigorous Demands in Today’s High Power Fast-Paced Design Landscape”
• This will be followed by a Panel Discussion with Dr. Kolar and Donna Kepcia who will host a discussion of topics of interest to the workshop attendees. Everyone’s participation is encouraged.
This opening technical session will be followed a special technical issues session covering measurement of ac power losses. In this session, a panel of six experts will each cover a specific issue associated with ac power loss measurements for fifteen minutes followed by a thirty-minute interactive panel Q&A discussion with the workshop attendees.

The presenters in this session include:
• Dr. Ray Ridley, Ridley Engineering, overview of general issues associated with ac power loss measurements
• Dr. Charles Sullivan, Dartmouth, Survey of Different Test Methods
• Bruce Carsten, Waveforms for Stimulating Magnetic Cores
• Santosh Kulkarni, Tyndall, Challenges to Improving the Accuracy of High Frequency (120 MHz) Test Systems
• Ed Herbert, PSMA, Parameter Extraction (Data Crunching)
• Chuck Wild, Dexter Magnetics, Industry Standardization
• This will be followed by a Panel Discussion where Dr. Ray Ridley, Dr. Charles Sullivan, Bruce Carsten, Santosh Kulkarni, Ed Herbert, and Chuck Wild will address topics of interest from the workshop attendees. Everyone’s participation is encouraged.

The third technical session, which will be coincident with lunch, is a series of interactive technology demonstrations and/or presentations addressing specific technical disciplines and capabilities consistent with the workshop agenda. Each of the individual technology demonstrations will repeat on fifteen minute intervals consisting of a ten-minute presentation and a five-minute Q&A. Workshop attendees are encouraged to move between the technology demonstrations so they can cover as many as possible during the session to allow reasonably small groups for each technology demonstration session.

The technical capabilities and disciplines that will be demonstrated and discussed during the technology demonstration session are as follows:
• JC Sun, Bs&T: DI/DT Measurements of Inductance
• Andreas Muesing, Gecko-Simulations: Developing Models and Simulations from Measurement Data
• Rodney Rogers, Allstar Magnetics: Correlation between Modelling and Measurements of a Common Mode Choke
• Bruce Carsten: Magnetics Characterization Test Equipment
• Ryu Nagahama, IWATSU: Core Loss Measurements on High Phase Angle Material
• Chris Oliver, Micrometals: Materials and Design Tools Suitable for 1 MHz+ Switching Frequencies
• Kevin McGivern, McGivern Technologies: Modelling Modular UR Cores
• Lorandt Foelkel, Wurth Elektronik: Calculation of AC Losses of Filter Inductors in Inverters
• Chuck Wild, Dexter Magnetics: Magnetic Supplier Technology Roadmaps
• National Magnetics: Rudy Geisler
• EPCOS, a TDK Group Company: Dr. Bernard Michaud, Jan Simecek
The fourth technical session will also feature two lecture style presentations. Each presenter will speak for thirty minutes followed by ten minutes for Q&A. The tentative schedule for this session is:
• Laili Wang, Sumida, will present “Package and Integration in Point-of-Load Converters”
• John Lynch, Fair Rite Products, will present “Developing Materials for High Frequency Power Magnetics”
• This will be followed by a Panel Discussion with Laili Wang and John Lynch who will host a discussion of topics of interest to the workshop attendees. Everyone’s participation is encouraged.
The fifth and final technical session will cover modelling of ac power losses. Three experts will cover a specific issue associated with modelling ac power loss for fifteen minutes and will be followed by a fifteen-minute interactive panel Q&A discussion with the workshop attendees.

The presenters in this session are:
• Dr. Charles Sullivan, Dartmouth, Overview of Modelling Methods
• Dr. Ray Ridley, Ridley Engineering: Spice Models for Conductor Losses
• Ed Herbert, PSMA: Spice models for Core Losses
• This will be followed by a Panel Discussion with Dr. Charles Sullivan, Dr. Ray Ridley, Ed Herbert who will host a discussion of topics of interest to the workshop attendees. Everyone’s participation is encouraged.

Following the final technical session there will be a networking hour. Wine, beer and hors d’oeuvre will be available from 5:00 to 6:00. There will also be an additional opportunity to visit with the technology demonstration stations during this period.

Registration for the Workshop is limited and interested attendees are encouraged to register today. The registration fee for the workshop is $300 per participant reducing to $200 for PSMA members, IEEE PELS members and students from an accredited university. After March 1, the registration fee increases to $350 reduced to $250 for members and students. Breakfast and lunch are provided as part of the workshop. Electronic copies of all presentations will be made available to the workshop participants via a password protected website.
