| Abstract: | This paper introduces the harmonic wave effect of automobile charging system to power grid.Restraining harmonic wave by trilevel PWM rectifier,it designs the rectifier circuit of voltage double closed loop.Sampling output direct voltage and input grid voltage,by PI adjuster,output voltage can become stable,and side current and voltage of power grid can become in-phase.Hence,the harmonic wave effect can be reduced and power factor can be improved. |
