Abstract :
A rectifier circuit architecture for achieving a power train conversion efficiency greater than 92% for a 12 kW rectifier for telecom applications is described for a design for a 380/480 V three phase AC input utilizing semiconductor devices with commonly available breakdown voltages is presented, including predicted and laboratory measurements of power train efficiency. An averaged model of the power train is developed in conjunction with a description of the control strategy
