Abstract
The application discloses a control method, a computer device, a controller, a charging system, a medium and a program product. The control method provided by the application embodiment can adjust the voltage of the DC bus multiple times through controlling different voltage conversion circuits. Compared with single adjustment, the multiple adjustment increases the adjustment range of the voltage of the DC bus, ensures that the voltage of the DC bus is within a safe voltage range, and ensures stable operation of the charging system. In addition, by gradually controlling different voltage conversion circuits, the control accuracy of the voltage of the DC bus can be improved. The voltage conversion circuit controlled each time can be designed according to an actual charging and discharging scene, so that the control method provided by the application embodiment is more suitable for the actual charging and discharging scene.
