一种具有内置变压器倍压单元的新型ZVS高升压变换器

This article proposes a novel interleaved high-step-up dc–dc converter with zero voltage switching (ZVS). Through a built-in transformer voltage multiplier cell (VMC) the high voltage conversion ratio is achieved without the narrow duty. By applying active clamp scheme, all of the power MOSFETs are switched with ZVS which minimizes the switching losses of the proposed converter. Besides the voltag...
