| description | The invention relates to a power supply switching circuit and a power supply system, the power supply switching circuit comprises more than two power supply circuits and a work control circuit, at least one power supply circuit is connected with a first power supply and a load, the first power supply is used for supplying power to the load when the power supply circuit is switched on, and the work control circuit is connected with the load. The at least one power supply circuit is connected with the work control circuit, the second power supply and the load, and supplies power to the load by using the second power supply during conduction; the work control circuit is connected with the first power supply and used for controlling the connected power supply circuit to be disconnected when the first power supply has power supply voltage and controlling the connected power supply circuit to be connected when the first power supply does not have the power supply voltage. The power supply circuits connected with th |
