Modeling and Analysis of Magnetic Components

Magnetic components, including inductors and transformers, are often the largest contributors to the size and loss of power converters, and can be a key limiting factor in achieving improved performance.  In this tutorial, we describe methods used to model magnetic components in both the electrical and magnetic domains.  The various modeling techniques introduced are valuable for expressing the behavior of magnetic components, for representing them for purposes of circuit modeling and design, and for the design of the components themselves.



David Perreault received the B.S. degree from Boston University and the S.M. and Ph.D. degrees from the Massachusetts Institute of Technology, all in Electrical Engineering.  He is presently the Joseph F. and Nancy P. Keithley Professor of Electrical Engineering and Computer Science at MIT.  His research interests include design, manufacturing, and control techniques for power electronic systems and components, and in their use in a wide range of applications.  Dr. Perreault is a Fellow of the IEEE and is the recipient of numerous awards including the IEEE R. David Middlebrook Achievement Award for his work in power electronics.  He has co-authored twelve IEEE prize papers in the area, and co-founded startup companies Eta Devices (acquired by Nokia in 2016) and Eta Wireless, Inc.


Alex Hanson received the BE degree from Dartmouth College in 2014 and the SM and PhD degrees in electrical engineering from the Massachusetts Institute of Technology in 2016 and 2019, respectively. In 2016, he received the William M. Portnoy award for his work on MHz-frequency magnetic components for power conversion. He is currently an Assistant Professor in the ECE department in the University of Texas at Austin in Austin, TX.  His research interests are in high-frequency power conversion, including magnetic components/materials, circuits, and systems.
Charles R. Sullivan is Professor of Engineering at Thayer School of Engineering at Dartmouth where he is also Director of the NSF Power Management Integration Center. He received a B.S. degree in from Princeton University in 1987 and a Ph.D. from the University of California, Berkeley in 1996. He has published over 200 technical papers and holds 42 US patents.  His research expertise includes modeling and optimization of electromagnetic components for high-frequency power conversion; thin-film magnetic materials and devices; and wireless power transfer.  He is a Fellow of the IEEE and the recipient of the 2018 IEEE Power Electronics Society Modeling and Control Technical Achievement Award, and co-founded Resonant Link, Inc.
