PSMA & PELS High Frequency Magnetics Workshop @ APEC 2017

PSMA Magnetics Committee and IEEE PELS High Frequency Magnetics Workshop

Power Magnetics @ High Frequency

 Transforming the Black Magic to Engineering

 

IEEE PELS and the PSMA Magnetics Committee will hold the second “Power Magnetics @ High Frequency – Transforming the Black Magic to Engineering” workshop on Saturday, March 25, 2017 -  the day before and in the same venue as APEC 2017 at the Tampa Convention Center.

The target audience for this workshop is all who wish to achieve higher power densities, low profile aspect ratio, higher efficiencies, and improved thermal performance.  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 can arrive to the meeting room between 7:00 AM to 8:00 AM for a buffet style breakfast and informal discussions with their colleagues and peers. There will be an opportunity to preview the technology demonstrations during the breakfast session.

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 as follows:

8:05 to 8:45. Dr. Johann Kolar, ETH, will present “Impact of Magnetics on Power Electronics Converter Performance – State of the Art and Future Prospects”

8:45 to 9:25. Donna Kepcia, Magnetics, will present “Smaller-Faster-Lower Cost—Magnetic Materials Meet Rigorous Demands in Today’s High Power Fast-Paced Design Landscape”

9:25 to 9:40:  Panel Discussion:  Dr. Kolar and Donna Kepcia will lead a panel discussion of topics of interest to the workshop attendees.  Everyone’s participation is encouraged.

The opening technical presentations will be followed a special technical issue session covering measurement of ac power losses. Each member of a panel of six experts will cover a specific issue associated with ac power loss measurements for fifteen minutes each followed by a thirty-minute interactive panel Q&A discussion with the workshop attendees. The tentative agenda for this session is as follows:

10:00 to 10:15. Dr. Ray Ridley, Ridley Engineering, overview of general issues associated with ac power loss measurements

10:15 to 10:30. Dr. Charles Sullivan, Dartmouth, Survey of Different Test Methods

10:30 to 10:45. Bruce Carsten, Waveforms for Stimulating Magnetic Cores

10:45 to 11:00. Santosh Kulkarni, Tyndall, Challenges to Improving the Accuracy of High Frequency (120 MHz) test Systems

11:00 to 11:15. Ed Herbert, PSMA, Parameter Extraction (Data Crunching)

11;15 to 11:30. Chuck Wild, Dexter Magnetics, Industry Standardization

11:30 to 12:00:  Panel Discussion:  Dr. Ray Ridley, Dr. Charles Sullivan, Bruce Carsten, Santosh Kulkarni, Ed Herbert, Chuck Wild will address topics of interest from the workshop attendees.  Everyone’s participation is encouraged.

The third session “Technology Demonstrations” will be coincident with lunch. This will be an interactive session of technology demonstrations and/or presentations each addressing specific technical disciplines and capabilities consistent with the workshop agenda. The individual technology demonstrations will repeat on fifteen minute intervals with a ten-minute presentation and a five minute QA during each interval. The workshop attendees are encouraged to move between the technology demonstrations on fifteen minute intervals so they can cover as many as possible during the session as well as to allow reasonably small groups for each technology demonstration session during each interval.

The technical capabilities and disciplines that will be demonstrated displayed 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 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 as follows:

2:00 to 2:40. Laili Wang, Sumida, will present “Package and Integration in Point-of-Load Converters”

2:40 to 3;20. John Lynch, Fair Rite Products, will present “Developing Materials for High Frequency Power Magnetics”

3:20 to 3:40:  Panel Discussion:  Laili Wang and John Lynch will lead a panel discussion of topics of interest to the workshop attendees.  Everyone’s participation is encouraged.

The fifth and final technical session a special technical issue session covering modelling of ac power losses. Each member of a panel of three experts will cover a specific issue associated with modelling ac power loss for fifteen minutes each followed by a fifteen-minute interactive panel Q&A discussion with the workshop attendees. The tentative agenda for this session is as follows:

4:00 to 4:15. Dr. Charles Sullivan, Dartmouth, Overview of Modelling Methods

4:15 to 4:30. Dr. Ray Ridley, Ridley Engineering: Spice Models for Conductor Losses

4:15 to 4:30. Ed Herbert, PSMA: Spice models for Core Losses

11:30 to 12:00:  Panel Discussion: Dr. Charles Sullivan, Dr. Ray Ridley, Ed Herbert will address topics of interest from 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 served from 5:00 to 6:00. There will be additional opportunity to visit with the technology demonstration stations during this session.

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, registration fee increases to $350 reduced to $250 for members and students. the Breakfast and lunch will be provided as part of the workshop. Electronic copies of all presentations will be made available to the workshop participants via a password protected website.

The latest information on agenda as well as registration information for the workshop will continue to be available on the PSMA website at: http://www.psma.com/technical-forums/magnetics/workshop .
