The first shutdown module includes a first switching device for controlling an output power of a first direct-current power supply coupled to a first input port; and the second shutdown module includes a second switching device for controlling an output power of a second direct-current power supply coupled to a second input port, where the control module modulates a power control signal and a first communication signal to generate a first composite control signal, and the first composite control signal controls the first switching device to work in a high-frequency switching state to superimpose a current ripple signal including the first communication signal onto a power bus; and the control module further generates a switching control signal, to control the second switching device.",
