Abstract :
A new soft switching chopper SAZZ(snubber assisted zero voltage and zero current transition) is extended to a bilateral converter for FCEV. The SAZZ topology has the advantages in (1) the turn-on loss is theoretically zero, (2) the turn-off loss is reduced by the snubber, (3) the number of the components is reduced. The experimental results with 8 kW output at 100 kHz switching frequency is presented with simulation results
