Abstract :
In this paper, an advanced two quadrant PWM chopper type DC-DC power converter with low switch peak voltage stress 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 soft switching PWM boost chopper type DC-DC converter is also proposed. These two circuit topologies are evaluated and compared on the basis of simulation and experimental results by a 1 kW, 50 kHz breadboard setup. Moreover, some modified circuit topologies of the soft switching boost chopper with coupled inductors are also discussed in this paper.
