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

mini projet report
Voltage source inverters (VSI) have been widely used in uninterruptible power supplies, unified power flow controllers or unified power quality conditioners, and distributed generation systems (DGS). VSIs are inherently efficient, compact, and economical devices used to control power flow and provide quality supply. VSIs can be classified as voltage-controlled VSIs (VCVSIs) and current-controlled VSIs (CCVSIs), depending on their control mechanism. In this paper, a detailed comparison of VCVSIs and CCVSIs for DG ....etc
