Abstract :
A high-quality rectifier for supplying resistive loads is presented. It features high power factor, low input current ripple and high efficiency. Device stresses are the same as for a buck converter, and input current is continuous. A suitable auxiliary network provides zero voltage switching for both power switch and diode. The ripple steering technique was applied in order to reduce the input current ripple. The converter, suitable for heating and lighting applications, was analyzed and experimentally tested on a 1 kW prototype
