The invention provides a control method of a vehicle-mounted bidirectional charger and the vehicle-mounted bidirectional charger. The method comprises the steps: responding to a working mode indicated by a charging and discharging instruction sent by a vehicle-mounted terminal, and controlling the current trend in a bidirectional DC/DC converter according to the working mode; and controlling the current direction in the bidirectional AC/DC converter based on the voltage sampling value of the bus and the reference voltage of the bus. The current trend in the bidirectional DC/DC converter is controlled according to the working mode indicated by the charging and discharging instruction, and the current trend in the bidirectional AC/DC converter is controlled according to the voltage sampling value of the bus and the reference voltage of the bus, so that the current trend in the bidirectional AC/DC converter and the current trend in the bidirectional DC/DC converter are smoothly switched, and the switching process of different algorithms is cancelled; and the impact on the power grid during traditional charging and discharging inversion can be reduced, and the safety of the power grid is improved.

    本申请提供了一种车载双向充电机的控制方法及车载双向充电机,包括:响应于车载终端发送的充放电指令所指示的工作模式,根据工作模式控制双向DC/DC变换器内的电流走向;基于母线的电压采样值和母线的基准电压,控制双向AC/DC变换器内的电流走向。本申请根据充放电指令所指示的工作模式控制双向DC/DC变换器内的电流走向,根据母线的电压采样值和母线的基准电压,控制双向AC/DC变换器内的电流走向,从而平滑切换双向AC/DC变换器和双向DC/DC变换器内的电流走向,取消不同算法的切换过程,因此能够减少传统充放电逆变时对电网的冲击,提高电网的安全性。
