DCM Analysis of ZVS PWM Full-Bridge Converter with Current Doubler Rectifier

Abstract:

The operation principle and the external characteristics in discontinuing current mode (DCM) are discussed for ZVS PWM Full-bridge Converter with current doubler rectifier (CDR ZVS PWM FB converter) .The converter operated in DCM remains the performances of the converter in CCM. This makes the converter achieve ZVS for the switches in a wide load range with the use of the energy stored in the output filter inductances, and the rectifier diodes commute naturally, therefore no oscillation occurs. Features of ZVS achievement for the switches in DCM are also included in this paper.
