THREE PHASE AC-DC RECTIFIER FOR EV-BATTERY CHARGING

Abstract

Electrification is the most viable way to achieve clean and efficient transportation that is crucial to the sustainable development of the whole world. In the near future, electric vehicles (EVs) including hybrid electric vehicles (HFVs), plug-in hybrid electric vehicles (PHEVs),and pure battery electric vehicles (BEVs) will dominate the clean vehicle market Charging of electric vehicle batteries inherently requires conversion of energy from the ac mains into dc quantities. Several charging voltage and power levels have been defined h\ different standardization organizations. Single-phase power f'actor corrector (PlC) mains interfaces are commonly employed for low power charging. whereas for higher power levels. three-phase PFC mains interfaces have to be applied. In this dissertation, a three-phase bucktype unity power factor rectifiers are studied for high-power electric vehicle battery charging mains interfaces
