The invention belongs to the technical field of vehicles, and particularly relates to a charging control method and device, a circuit topology, an energy conversion device and a vehicle. In the present application, according to a first control signal, a second control signal and a third control signal in the three-phase control signals which are sequentially different in a pre-phase, the alternateconduction of the two power switches in the three-phase bridge arms in a bridge arm converter are separately and correspondingly controlled, so that a battery is charged, and the purposes of reducingthe direct-current side ripples and improving the charging power are achieved.
本申请属于车辆技术领域,尤其涉及一种充电控制方法、装置、电路拓扑、能量转换装置及车辆。在本申请中,本申请通过根据依次相差预相位的三相控制信号中的第一控制信号、第二控制信号以及第三控制信号分别对应控制桥臂变换器中的三相桥臂中的两个功率开关的交替导通,以对电池进行充电,以实现减小直流侧纹波,并提高充电功率的目的。
