The utility model relates to a can be many machines that charge that electric automobile charges simultaneously, including a plurality of be used for with ac inversion for galvanic power converting module, the power converting module is divided into two sets ofly at least, on the every power converting of group module and dc bus one -to -one, the output of the every power converting of group module all were connected to corresponding dc bus, every at least two of dc bus output connection was used for the circuit that charges that charges for electric automobile. The machine that should charge can satisfy a plurality of electric automobile and charges simultaneously through setting up a plurality of circuits that charge, has made things convenient for the user to charge, a dc bus is answered to the every power converting of group pair of module, and the dc bus autonomous working is interference -free each other, if wherein have partial dc bus or power converting module to break down, with trouble generating line or module excision, all the other dc buss or power converting module still can normally be worked, and be interference -free, has promoted the reliability and the flexibility of the machine that charges.
