Comparative study of Full-Bridge and Double Half-Bridge converters

A comparative study of two isolated DC-DC ZVS converters topologies is described in this paper, one of them is the Full-Bridge topology considered the most used in the field of DC-DC power conversion for high power applications, which will be compared with a Double Half-Bridge topology counterpart, both operating in ZVS phase-shifted PWM. Operation stages for both topologies are described, analyzed, designed, simulated and compared, where Double Half-Bridge DC-DC ZVS converter allows to operating from no-load to full-load, as well as it can operate at output voltage full range, at zero voltage commutation.
