The paper presents high-frequency isolated soft-switching DC–DC converter for generating regulated high output voltage from fuel cell power modules using secondary-side phase-shift control to eliminate idling and circulating currents. The converter topology incorporates high-frequency center tap transformer with secondary-side phase-shift soft-switching control. Parasitic capacitors of the switching...
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...
