具有紧凑结构的宽负载范围ZVZCS三电平DC-DC变换器

To fit the requirements of high input dc–dc power conversion, a novel zero-voltage and zero-current switching (ZVZCS) three-level dc–dc converter is proposed. Some advantages of the proposed converter are concluded as follows. The off voltages on the primary switches are clamped around Vin/2 by the input capacitors and the blocking capacitor. A total of two mosfets with low VA rating are added to ...
