ENGG 199.3 - High-Frequency Power Magnetics Design


One of the fundamental advantages of power electronics is the ability to use high frequencies which enable reductions in physical size, weight and cost of passive components such as magnetics with losses also reduced. However high-frequency effects in both magnetic cores and in windings rapidly increase power losses at higher frequencies limiting performance and inhibiting the use of increased frequency to yield further improvements. After a review of magnetics modeling and design fundamentals, the class will examine best-practice techniques for high-frequency magnetics modeling and design. Selected recent and current research in modeling, design, and fabrication will be examined in detail, including self-resonant passive components. Finally, applications to wireless power transfer will be studied.
