Abstract

An advanced two-quadrant PWM controlled chopper type DC-DC power converter with lowered peak switch voltage stress, which is effectively used for parallel processing type small-scale UPS applications and utility interactive new energy interface distributed power supplies, is presented. In addition, a coupled inductor-assisted zero-voltage soft-switching PWM step-up chopper controlled type DC-DC power converter is also proposed and discussed. These two DC-DC converter circuit topologies are evaluated and compared on the basis of simulation and experimental results by a 1 kW 50 kHz breadboard setup using MOSFETs. The electromagnetic conductive noise characteristics of both converter circuits are also compared through experimentation.
