摘　　要：介绍了软开关技术的基本原理、基本的软开关电路拓扑,提出一种开关磁阻电机功率变换器的软开关方案,该方案在直流电源与相绕组控制电路间插入一种准谐振直流环节电路,并给每个相开关并联电容器后实现了开关磁阻电机功率电路中所有器件的软开关操作。对主电路工作模式进行了分析,并通过仿真验证了所提电路的软开关性能。Based on the soft-switching rationale and basic topological structure of soft-switching circuits, a brand-new soft-switching converter for SRM was proposed, which is made up of a kind of quasi resonant DC link circuit and a typical SRM converter employing least switch devices. All power switch devices of the proposed converter are able to operate in soft-switching mode. The soft-switching operation mode was analyzed. Simulation results are also presented to validate the proposed scheme.
