The Comparison and Analysis on Harmonic Suppression of EV Charging Station

Abstract

In order to propose reasonable method of harmonic suppression for EV charging station, three methods that are 6-pulse rectifier with APF, 12-pulse rectifier, PWM rectifiers are analyzed and compared. Firstly,the corresponding simulation model of charger and charging station are built based on the principle of EV charger and the main method of harmonic suppression. Then the harmonic content and power factor for different simulation model are researched. Meanwhile, the advantages and disadvantages of different simulation model are studied according to the results of simulation, the use of performance and economy. At last, the improvement measure and development direction for three methods are proposed.
