Abstract

A series LC resonance-pulse assisted current-fed three-phase converter has been proposed and investigated in this article. The aim is to present a simple and practical high boost topology that achieves zero current switching (ZCS) of the semiconductor devices and regulates the output voltage for wide source voltage and load variations. Resonance characteristics were exploited during short switching overlap time to cause natural commutation of the active devices eliminating turn-off voltage spike along with reduced circulating currents in the converter. Current-sharing three inductor methodology has been employed resulting into reduced current stresses on the primary side semiconductor devices and reduced heat sink requirements. In addition, the gate driving and control requirements are simpler due to devices having common ground with the supply thereby improving the overall conversion efficiency. Output voltage is regulated by employing variable frequency control. The proposed converter analysis and design are validated using simulation results from PSIM 11.01 Software.
