Power Magnetics @ High Frequency
Transforming the Black Magic to Engineering
Date: Saturday March 25, 2017
Tampa, Florida
 he PSMA Magnetics Committee and IEEE PELS are organizing the second “Power Magnetics @ High Frequency – Transforming the Black Magic to Engineering” workshop to be held on Saturday, March 25, 2017 - the day before and in the same venue as APEC 2017 at the Tampa Convention Center.
The organizing committee is currently working on the specifics for the workshop structure and the presentations. The primary focus of the workshop is to address 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 to meet the evolving market needs. The technical expectations and requirements for higher application frequencies and emerging topologies are being driven by recent advances in circuits topologies and semi-conductor devices to satisfy new market applications.
The target audiences for the workshop include the designers of power magnetic components for use in electronic power converters to achieve higher power densities, specific physical aspect ratios such as low profile, higher power efficiencies, improved thermal performance etc. Other target audiences are the manufacturers of magnetic materials and magnetic structures, the fabricators of magnetic components, the providers of modelling and simulation software as well as the manufacturers of test and characterization equipment who are all critical participants in the supply chain for the power magnetics industry.
The agenda of the workshop is designed so that there will be keynote presentations by invited speakers followed by question and answer forum addressing the latest trends in:
- conductor geometries and magnetic core geometries for reducing physical size while minimizing ac power losses
- magnetic materials
- design and fabrication (manufacturing) techniques
- design techniques, simulation tools and modelling
- power conversion topologies and applications driving the reduction of the physical size while improving the efficiency of power magnetics technologies
The keynote presentations will be followed by an interactive session of table top technology demonstrations each addressing specific technical disciplines and capabilities consistent with the workshop agenda. The session will begin with a brief overview and mapping of up to nine technology demonstration stations. Current plans are for each technology demonstration station to provide a ten-minute presentation. Interaction between the attendees and the presenters will be encouraged during this portion of agenda as a segue from the opening keynote presentation and the technical issues session which will follow. The technical disciplines expected to be displayed during the technical demonstration session include:
- AC power loss measurements
- Core loss modelling and/or simulation with empirical verification
- Inductor modelling supported by empirical verification
- Near magnetic field measurements
- Thermal measurements
- Impedance measurements
- Engineering methodology specific to new structures and/or magnetic materials including both modeling and verification
- Roadmaps addressing the needs of the power magnetics industry
- Standardization activity addressing any of the above topics
The third session of the workshop will be a technical issues session. Three potential technical issues have been proposed based upon responses to the attendee survey conducted after last year’s workshop. These are:
- engineering magnetic materials and structures for emerging applications,
- engineering, physical, electrical and thermal integration of magnetics into power supplies, and
- engineering technical and manufacturing trade-offs to include safety agency requirements during commercial product development.
The presenter for each technical issue will provide typical traditional engineering solutions and discuss several alternative engineering approaches to the technical issue before focusing on the solution that they will propose.
The fourth and final session is currently planned to be a combination of a wrap-up session followed by small focus group discussions. The first portion of this session would be identification of items to be addressed by a roadmap for the magnetics industry covering de-facto industry practices and standards and emerging trends as well as both short term goals covering incremental improvements and longer term evolutions that are on the horizon. The second portion of this session will allow additional interaction between the attendees and the presenters on a one on one or in small focus groups.
The organizing committee welcomes suggestions for specific topics that would be of general interest to the magnetics and the power industries. In addition, the committee welcome proposals for participating as a presenter in the technical demonstration session and proposals for technical issues that should be addressed. Please contact power@psma.com with your suggestions and proposals or contact Matt Wilkowski of the organizing committee at mwilkows@altera.com.
The latest information on agenda as well as registration information for the workshop will become available on the PSMA website over the next few months at: www.psma.com/technical-forums/magnetics/workshop .
