Modern Magnetic Technology
Rompower Energy Systems Inc. Founder and CEO Ionel “Dan” Jitaru will be presenting the “Modern Magnetic Technology” Seminar at the APEC conference.
Schedule: Monday, 3/18/2019, 9:30 a.m. – 12:00 p.m.
Destination: Anaheim Convention Center, 800 W Katella Ave, Anaheim, CA 92802
There was a significant progress in semiconductor technology in the last twenty years which pushed the power conversion efficiency from low to middle 80% to low to middle 90% over the last twenty years. During the same time period the progress in magnetic technology was practically negligible. We all were waiting for a “miracle” new core material which will allow us to make the next jump. Though not much publicized, in magnetic technology there were many new ideas but these ideas did capture just fragments of the market due the proprietary nature of these new technology. Some of these new ideas are in public domain these days but many of the engineers were not expose to them.
The goal of the seminar is to bring some light into the modern magnetic technologies and to teach the engineers how to rethink the magnetic design for high efficiency and high power density.
The seminar will present a comprehensive overview of the modern magnetic technologies presently used in power conversion and new trends in magnetics aimed to address the new demands in power conversion. In the quest for higher power densities and higher efficiency magnetic technologies were forced to adapt and then new magnetic structures were developed.
The seminar will start by presenting several key characteristics of magnetic transformers such as leakage inductance, stray inductance, inter-winding and intra-winding capacitance and their impact in power conversion performance. Methods of measuring and controlling these parasitic elements are also presented. The seminar will present experimental results
and methods of measuring the key magnetic parameters for application ranging from low power transformers for adapters to several KW transformers for server and telecom applications.
The seminar will also show some present and future trends in magnetics for higher frequency operation. A chapter will be dedicated to the new trends in magnetic technology for very high efficiency applications.
These new magnetic technologies are compatible with the latest technologies in power conversion aimed at very high efficiency and very high power density. The seminar will address different applications such
as 30W-65W AC-DC power adapters to multiple KW DC-DC converters and Power Factor Correction modules with very high efficiency. The presentation will be highlighted with design guidance, design
example and experimental results.
