Integrated Magnetics Design for a Three-Phase Differential-Mode Rectifier

Abstract

In this article, the design methodology of integrated magnetics (IM) for a three-phase differential-mode Ĉuk rectifier (DMCR) is outlined. The design and optimization of the IM are so achieved such that the inductor current ripple, total harmonic distortion of the input current, and magnetics loss are optimized without compromising the stability of the DMCR. The optimization and design of the IM are conducted using the Maxwell and SaberRD software tools, and subsequently, the results are compared with a plurality of other IM structures for performance comparison. Finally, the experimental hardware for the DMCR comprising the optimized IM is fabricated to validate its performance and compare it with a DMCR fabricated solely using discrete magnetics.
