Abstract :
This paper compares three soft-switched fixed-frequency high-frequency transformer isolated DC-DC converters designed for the given specifications. Three configurations compared are (a) phase-shifted PWM full bridge converter, (b) hybrid phase-modulated converter (HPMC) with inductive output filter, and (c) HPMC with capacitive output filter. It is shown that HPMC with capacitive output filter is useful for high output voltage applications and has superior characteristics compared to other two configurations.
