Power electronic converters are expected to be significant contributors to system mass, system loss, and system cost in the all-electric ship, and are therefore a significant area of interest. This paper investigates the reduction of switching losses in high power (MW level) converters. These losses remain a major obstacle to the development of converters capable of operating at higher frequencies and higher power densities. The Auxiliary Resonant Commutated Pole (ARCP) soft-switching converter topology offers the potential for minimization of switching losses but has some inherent limitations. This paper examines two new converter designs based on the ARCP soft-switching topology that allow for more compact units by reducing the semiconductor switching losses generated within them. These concepts have been proven in principle by preliminary laboratory testing of a scaled 20 kW converter prototype. The new proposed topologies are described and simulation results and experimental waveforms obtained on the prototype unit are also reported.
