一种带同步整流的软开关非对称飞跨电容升压变换器

The multilevel flying-capacitor boost converter was analyzed for asymmetric voltage operation—this permits loss optimization that takes advantage of different voltage class MOSFETs. A cost-motivated design of a suitable zero-voltage zero-current switching snubber is then developed that permits a great reduction of the inductor size. With the proposed snubber, synchronous rectification operation is...
