"textContent": "A UPS electricity supply control circuit and a UPS electricity supply. The present UPS electricity supply comprises a rechargeable battery and a UPS electricity supply control circuit connected to said rechargeable battery. Said UPS electricity supply control circuit comprises an input filter circuit, a rectifier circuit, an inverter circuit, a static transfer switch, an output filter circuit, a control circuit, and a DC/DC multiplexer circuit disposed between said rechargeable battery and an output of said rectifier circuit. Said DC/DC multiplexer circuit is controlled by said control circuit. During a mode in which the battery provides electricity, said rechargeable battery provides an input voltage for said inverter circuit through said DC/DC multiplexer circuit. During a mode in which an alternating current provides electricity, the output voltage of said rectifier circuit recharges said rechargeable battery through said DC/DC multiplexer circuit. Hence, no independent recharging circuit is needed to recharge the rechargeable battery, thereby simplifying the overall circuitry of the UPS electricity supply control circuit, lowering the cost, and providing users with greater value.",
