Review of current quality compensators for high power unidirectional electric vehicle battery charger

This paper reviews and compares different possible current quality compensating solutions for a high power unidirectional electric vehicle (EV) battery charger with three-phase power supply. Their pros, cons and characteristics for the high power EV battery charger are also summarized. Simulation results of different compensating solutions for a 50kW EV charging system are also provided to illustrate and compare their compensating performances and characteristics.
