The car industry pushes very fast toward electric vehicles (EVs). AC to DC charging stations pose big challenges for the power grid due to the heavy stress caused by electric-powered vehicles, especially when many vehicles are loading their accumulators simultaneously. The commercial success of electric vehicles (EVs) relies heavily on the presence of high-efficiency charging stations with low harmonics and a good power factor. To improve the power factor and boost the output voltage, this paper presents an analysis study and a simulation model of a 12-pulse high-power AC/DC active rectifier for EV charging stations. This converter topology provides bidirectional power flow and plays a double role as an AC to DC converter for power factor correction and as a DC converter for output regulation. The converter circuit is simulated using PSIM software, and results have observed. The simulation results for different conditions of operation are presented to highlight the feasibility and advantages of the proposed active rectifier.
