Abstract :
In this paper a study for very high efficiency targeting 99 % range converter is described. We have proposed a new soft switching boost type chopper based on snubber assisted zero voltage and zero current transition (SAZZ) with output diode fabricated ldquoSiC schottky dioderdquo. The output power of 8 kW with the efficiency of 98.96% was obtained. The loss breakdown evaluation of SiC-SAZZ is discussed.
