Simulation and Modeling to Non-Car Charger Electric Vehicles of Based on MATLAB

On the basis of describing the basic structure of the electric vehicle(EV),the high–frequency isolated DC/DC converter and the steering circuit of off-board charger was analyzed according to the basic principle of the off-board charger,which was especially suitable for the three-phase uncontrollable rectified charger.Based on the matlab-simulink,the off-board charger of EV was modeled,and some correlation parameters were calculated in simulation system as well.Moreover,some evaluations about the quality of the input’s and output’s electric energy were made in this paper.
