Modeling and control of a 50KW Electric Vehicle battery fast charger Power Factor Correction stage, developed at Gamatronic Electronic Industries LTD, is presented in the paper. The charger topology may be referred as a two-stage controlled rectifier. The input stage consists of a three phase full bridge rectifier combined with an active power filter (three single stage power filters are actually employed). The input stage creates an uncontrolled DC bus while complying with the grid codes by keeping the THD and power factor within the permissible limits. The output stage is formed by twelve DC-DC converters and is perceived as a constant power load by the input stage. The active power filter is operated using all-analog control circuitry according to the predetermined grid interfacing behavior. Input stage hardware and control loops are explained throughout the paper and extended simulation/experimental results are presented.
