The multi-power supply system includes a first power-supply unit, a second power-supply unit, a switching unit, and a control unit. The power-supply unit comprises a reverse current prevention circuit, a converter circuit, and an input circuit. The switching unit is electrically coupled to the first power-supply unit and the second power-supply unit. When the first and second input circuits are in normal operation, the control unit controls the switching unit to be turned off to allow the first power-supply unit and the second power-supply unit to supply power to a load. When one of the first and second input circuits is in abnormal operation, the control unit controls the switching unit to be turned on. The switching unit cooperates with the first and second reverse current prevention circuits to achieve the switching of input."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-power supply system and control method thereof","description":"A multi-power supply system and a control method thereof are disclosed.
