PSMA and PELS Magnetics Committee High Frequency Magnetics Workshop 

Power Magnetics @ High Frequency
Saturday March 14 2020
Prior to APEC 2020
Ernest N. Morial Convention Center
New Orleans, LA

The PSMA Magnetics Committee and IEEE PELS will conduct the fifth "Power Magnetics @ High Frequency" workshop on Saturday, March14, 2020, which is the day before and at the same venue as APEC 2020 in New Orleans, LA.

The target audiences for the 2020 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 people 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 purpose and focus of the workshop is to identify the latest improvements in magnetic materials, coil (winding) design, construction and fabrication. The workshop will include 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. These emerging topologies are being driven by continuous advances in circuits topologies and semi-conductor devices required by new market applications.

The workshop will consist of two technical lecture presentation sessions, an interactive technology demonstration session and a wrap up session summarizing the presentations and their potential impact on the power electronics community. The two technical lecture sessions will each be followed with a panel Q&A session. The technology demonstrations will also be available during the breakfast just prior to the opening session of the workshop, during lunch and during the networking session following the workshop’s formal presentations.

The morning technical presentations will be on Modelling and Characterization beginning with a keynote presentation by Tom Wilson of SIMPLIS Technologies that addresses the challenges of modelling non-linear properties of power magnetic components. Tom will touch upon topics such as creating models for conductor losses that take into account distribution of the conductors and their position relative to the air gap and creating models for core losses that take into account variations due to dc bias and temperature from core loss measurements made with triangular flux excitation. Tom will present an example of a design for an LLC dc-dc converter demonstrating the impacts of various design options based on modelling the non-linear properties of magnetic components.

Mike Wens of MinDCet will provide a presentation on the characterization of magnetics with large signal waveforms that are representative of the actual operating waveforms. Presenters are being confirmed to discuss  the topic of FEA simulations considering both linear and non-linear properties of magnetic materials, the topic of measurement methods and deriving loss models from test measurements and the topic of use of FEA simulations to develop inductor and transformer parameters for spice modelling of different winding techniques. The morning session will be followed with a panel Q&A consisting of the morning’s presenters.

During the breakfast, lunch and network hour sessions there will be interactive technology demonstration presentations where 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. The confirmed technology demonstrations at this time include:

  • real time inductor design using artificial intelligence (Frenetics),
  • modelling and simulation of nonlinear magnetics (SIMPLIS Technologies),
  • pulse characterization of magnetic components (Bs&T),
  • inductance characterization of magnetic components in the MHz frequency range with a bias range of 0 ADC thru 125 ADC (Omicron Lab),
  • thermal behavior of power inductors at high frequency operation (Wurth Elektronik),
  • impact of leakage inductance on performance of SEPIC/CUK dc-dc converter (Wurth Elektronik),
  • impact of permittivity on core losses (Rodney Rogers), and
  • recent advances in iron composite powder cores (Micrometals)

Additional technical demonstrations are currently being considered for computer aided design of power magnetic components, tradeoffs between vector network analyzers, near magnetic field characterizations, impedance analyzers and LCR meters for characterization of magnetic components and emerging magnetic materials and structures for commercial applications.

Attendees will also be able to visit the technical demonstrations for the Capacitor Workshop “How to Choose and Define Capacitor Usage for Emerging Applications” that will be held concurrently.

The afternoon session will be a Survey of Winding Techniques Used in Power Magnetic Components. The session will begin with a keynote presentation by Dr. Charles Sullivan of Dartmouth University that will provide a technical overview of various winding techniques used to achieve specific technical performance goals as well as an overview of the topics to be covered in the afternoon session.

Jannik Schafer of ETH Zurich will speak on the design of PCB winding inductors employing the CCFC Compensating Fringing Field Concept. There  will also be presentations of unique winding structures from different manufacturers as well as presentations of the design considerations for copper foil, stranded wire and litz wire coil constructions. The afternoon session will be followed with a panel Q&A consisting of the afternoon’s presenters.

The workshop will conclude with a general review of the workshop presentations and their potential impact to improve the power electronics industry by Alexander Gerfer of Wurth Elektronik.

Following the closing remarks will be a networking hour with hors d'oeuvres, soft drinks, wine and beer from 5:00 to 6:00. This will provide an additional opportunity to visit the technology demonstration stations.

The registration fee for the workshop is $360 per participant reducing to $260 for PSMA members and IEEE PELS members. On February 1, 2019 the registration fee will increase to $400 reducing to $300 for PSMA members and IEEE PELS members. The day of workshop registration fee will be $425 reducing to $325 for PSMA members and IEEE PELS members if seating is available. There is an option at a nominal fee of $5 to obtain Continuing Education Units (CEUs) for attending in this workshop. 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.

PSMA Magnetics Committee and IEEE PELS High Frequency Magnetics Workshop

Power Magnetics @ High Frequency
Date: Saturday March 14, 2020
APEC 2020, New Orleans, Louisiana

The High Frequency Magnetics workshop series will continue to be held the Saturday before APEC. The fifth workshop of the series will be in conjunction with APEC 2020 in New Orleans, Louisiana. The post workshop survey of the recent 2019 workshop has identified two themes -winding techniques and characterization and modelling. The survey results also proposed a pool of both volunteer presenters and requested presenters. The workshop will also make available Continuing Education Credits (CEC) to workshop attendees going forward. The workshop organizers will continue the tradition of the first four magnetics workshops, held each year since 2016, by bringing together experts from all aspects of the magnetics industry research and academic organizations, world renowned consultants and the everyday heroes of magnetics design who are responsible for commercializing magnetic products on a regular basis to address the two major themes: winding techniques and characterization and modelling.

 

The fourth Power Magnetics @ High Frequency workshop sponsored by the PSMA Magnetics Committee and IEEE PELS was held on the day before APEC 2019, Saturday March 16, 2019 from 7:00 AM thru 6:00 PM in Anaheim California. There were 110 attendees, with about 78% of the attendees from industry and 22% from academia/research. The consensus was "… the workshop was much more intimate with productive and valuable interaction between the presenters and the attendees…" which derives from the structure of the workshop, including panel discussions and technology demonstrations to supplement traditional lecture type presentations, which lead to high energy dialogue between the attendees and the invited experts throughout the workshop.

This fourth workshop addressed two specific focus area: ac power losses and thermal considerations for power magnetic components.
