The invention provides a driving control method, device and system of a three-port vehicle-mounted converter and a vehicle. According to the method, the working state of the primary side conversion circuit is identified, the on-off state of a power tube in the primary side conversion circuit is combined to carry out turn-off control on a first switching tube in the low-voltage conversion circuit, turn-off control is carried out at the time point of the minimum current, and due to the minimum current, the stress is minimum, and loss generated during turn-off is minimum. Compared with an existing control mode, the control mode of the embodiment is simpler and more reliable, and the cost is also low.
本申请提供了一种三端口车载变换器的驱动控制方法、装置、系统和车辆。该方法通过识别出原边转换电路的工作状态,结合原边转换电路中功率管的通断状态对低压转换电路中第一开关管的关断控制,实现在电流最小的时间点进行关断的控制,由于电流最小,所以其应力最小,在关断时产生的损耗也最小。相比于现有的控制方式,本实施例的控制方式更加简单可靠,成本也低。
