一种器件数量减少的ZVZCS全桥三电平DC/DC变换器

This letter proposes a new zero-voltage and zero-current switching (ZVZCS) full-bridge (FB) three-level dc/dc converter (TLDC) with the reduced device count. The merits of the proposed converter with the corresponding modulation strategy are concluded as follows. In comparison with the zero-voltage-switching FB TLDC: 1) only one blocking capacitor is added to realize the ZVZCS strategy, 2) the pri...
