High-Power Charger with d-q Control and Conventional Buck Converter for Fast Charging a City Car

As part of improving the competitiveness of city electric vehicles in terms of cost and fuel emission issues, this article comes to respond to these challenges. In fact, a high-power charger based on three-phase source is proposed. This charger is designed to reduce recharging time while maintaining good quality electrical energy taken from the electrical distribution grid. Two power stages are designed. And a control d-q strategy is implemented, on the AC–DC side for a better power factor, and a constant current constant voltage algorithm is used in the  DC–DC side to charge the battery. Thus, to achieve this goal, the theoretical topology is discussed and a simulation is done under Matlab/Simulink.
