A High Input Voltage Three-Phase ZVZCS DC-DC Converter with Vin /3 Voltage Stress on Primary Switches
Abstract
A high-voltage three-phase ZVZCS dc-dc converterwith low voltage stress is presented in this paper. The voltagestress on the primary switches is only one-third of the inputvoltage. By using the phase shift pulsewidth modulation (PWM)and secondary snubber, four of the six primary switches areoperating with zero-voltage switching (ZVS) and two of them areoperating with zero-current switching (ZCS), in order to reducethe switch ....etc

Abstract—
This paper proposes a new soft-switched continuousconduction- mode (CCM) boost converter suitable for high-power applications such as power factor correction, hybrid electric vehicles, and fuel cell power conversion systems. The proposed converter achieves zero-voltage-switched (ZVS) turn-on of active switches in CCM and zero-current-switched turn-off of diodes leading to negligible reverse-recovery loss. The components’ voltage ratings and energy volumes of passive components of the proposed converter are greatly reduce ....etc
