An on-board charger system, and a method and a device for controlling the on-board charger system to switch between operating modes are provided. An operating mode switching signal for the on-board charger system is acquired. A to-be-started power module in the on-board charger system is controlled, based on the operating mode switching signal, to start in a current source mode and adapt a given current to an operating condition until a power demand of the system is met. The to-be-started power module is switched to a voltage source mode, and controls the voltage across the direct current bus. Throughout the switch, a voltage across a direct current bus in the system remains unchanged.
