Abstract

This paper studies the implementation of three-phase DC-DC power converters for high current, high power applications. The frequency adjustment for constant voltage, and constant current operation of an LCC series-parallel resonant power converter are determined. An LCC resonant power converter and a PWM power converter are analyzed, designed and experimentally tested at a current of 700 A, and a power of 5 kW. Conclusions are drawn regarding the most feasible solution
