基于SiC软开关三相AC-DC变换器的PCB绕组耦合电感设计与共模EMI噪声抑制

This article presents a PCB winding coupled inductor design for both high efficiency and effective common-mode (CM) noise reduction in a silicon carbide (SiC)-based soft-switching three-phase ac–dc converter. A balance technique is applied to reduce the CM noise, creating a return path with additional inductors. The inductors in the main circuit and return path are coupled in one core and implemen...
