Abstract :
This paper discusses overcoming the limitations of an auxiliary resonant commutated pole (ARCP) power converter topology caused by high-frequency switching and tail current losses in the power devices. The analytical simulation and test data comparison demonstrate the benefits of adding an output commutating switch to ARCP topology for use in DC-DC power converters whose input voltage exceeds 800 V DC. The performance of a soft-switched DC-DC converter from 1100 V DC into a regulated and isolated 270 V DC output at 20 kHz switching frequency is compared to hard switching
