The invention belongs to the technical field of new energy vehicles, and particularly relates to a voltage control method, charging and power distribution equipment, a medium, a vehicle-mounted power supply and a vehicle. On the basis of a three-port topological structure, under the condition that only a second port B provides direct-current battery energy and a first port A on an alternating-current side is blocked, when energy is transmitted to a third port C along with the second port B through a three-winding transformer in the three ports, a controllable switch bridge circuit at the first port A is adjusted, so that the energy is transmitted to the third port C through the three-winding transformer in the three ports; a discharge operation is performed to control the port voltage; capacitance-inductance resonance at the first port A is eliminated, so that the risk of overvoltage possibly generated is eliminated; according to the method and the product, on the premise that an original topological structure is not changed, the stability and the reliability of integration of a three-port topological structure on-board charger (OBC) and a direct current (DC)-direct current (DC) conversion system can be improved by introducing a voltage control process, and therefore the stability and the reliability of integration of the three-port topological structure on-board charger (OBC) and the direct current (DC)-direct current (DC) conversion system can be improved.
本发明属于新能源车技术领域,尤其涉及一种电压控制方法、充配电设备、介质、车载电源及车辆;在三端口拓扑结构的基础上,对仅由第二端口B提供直流电池能量,而交流侧的第一端口A被封锁的条件下,伴随该第二端口B向第三端口C通过该三端口内部三绕组变压器传输能量时,通过调整其第一端口A处的可控开关桥电路,并实施放电操作来控制端口电压;消除第一端口A处电容电感谐振,进而可能产生过压的风险;该方法和产品可在原有拓扑结构不变的前提下,通过引入电压控制过程,改善三端口拓扑结构车载充电机OBC(On Board Charger)与直‑直DCDC(Direct Current to Direct Current)变换系统集成的稳定性和可靠性。
