Title:
POWER DISTRIBUTION CIRCUIT, METHOD FOR CONTROLLING POWER SUPPLY OF POWER DISTRIBUTION CIRCUIT, AND POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/216566
Kind Code:
A1
Abstract:
The present application relates to the technical field of power supply, and provides a power distribution circuit. The power distribution circuit comprises: an alternating-current power input end, a direct-current power input end, an alternating-current load input end, a direct-current load input end, a switch circuit, a direct-current/alternating-current converter, a direct-current/direct-current converter, and a control unit; the switch circuit is coupled between the alternating-current power input end and the alternating-current load input end; one end of the direct-current/alternating-current converter is coupled to the switch circuit and the alternating-current load input end, and the other end is coupled to the direct-current power input end and the direct-current/direct-current converter; one end of the direct-current/direct-current converter is coupled to the direct-current/alternating-current converter and the direct-current power input end, and the other end is coupled to the direct-current load input end; the control unit is electrically connected to the switch circuit, the direct-current/alternating-current converter and the direct-current/direct-current converter. The power distribution circuit can convert alternating-current power, which is input from a mains supply system, into stable direct-current power and stable alternating-current power, so as to provide stable electrical signals for an alternating-current load and a direct-current load.
