The The invention relates to an electric power conversion system for a vehicle and a control method thereof. The electric power conversion system includes: an AC-DC conversion circuit converting AC charging power into DC power; a motor including a plurality of coils, one end of each being connected to a neutral point; a first switching device selectively allowing or blocking supply of output powerfrom the AC-DC conversion circuit to the neutral point; an inverter including a plurality of motor connection terminals connected to the other ends of the coils of the motor, respectively, DC connection terminals including a positive terminal and a negative terminal, and a plurality of switching elements forming electrical connections between the DC connection terminals and the plurality of motorconnection terminals; a battery connected to the DC connection terminals of the inverter; and a controller controlling operations of the AC-DC conversion circuit, the first switching device, and theinverter in accordance with whether or not the battery is charged.
本申请涉及用于车辆的电力转换系统及其控制方法。一种电力转换系统,包括:AC‑DC转换电路,将AC充电电力转换成DC电力;电机,包括多个线圈,每个线圈的一端连接至中性点;第一切换设备,选择性地允许或阻止将输出电力从AC‑DC转换电路供应至中性点;变换器,包括分别连接至电机的线圈的另一端的多个电机连接端子、包括正极端子和负极端子的DC连接端子、和形成DC连接端子与多个电机连接端子之间的电连接的多个切换元件;电池,连接至变换器的DC连接端子;以及控制器,根据电池是否被充电来控制AC‑DC转换电路、第一切换设备以及变换器的操作。
