| Abstract: | The electric power circuit topology structure of electric vehicle(EV) charger has been designed in this article,and a detailed analysis of the working principle of three-phase pulse width modulation(PWM) voltage source rectifier(VSR).At the same time, considering the characteristics of EV charger,power factor and charging efficiency are optimized in performance,combined with the control method of the actual circuit has been improved.Using MATLAB/SIMULINK tool for the simulation of the circuit topology and control method,and the results show that the design scheme of charger is right and the soft-switching technology is effective;Compared with the conventional rectifier,DC-Side voltage is stable and the ripple is smaller,AC-Side current is nearly sinusoidal,and the phases of voltage and current are consistent,which can greatly improve the power factor,while the efficiency of charge. |
