摘要： A power supply system and method. The power supply system comprises: a power grid input unit (101) and a diesel generator input unit (102), separately used for supplying an alternating current to a power supply unit (104); an automatic transfer switch unit (103), connected to the power grid input unit and the power supply unit or connected to the diesel generator input unit and the power supply unit; the power supply unit, used for converting the received alternating current into a direct current; and a control unit (105), used for monitoring a current load current and current diesel generator power, and determining to turn off a preset number of power supply loads according to a magnitude relationship between the current diesel generator power and the current load power and according to priority levels of current loads. By means of the power supply system and method, the power supply time is prolonged and the power supply reliability is improved.

摘要： 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.

摘要： A DC/DC circuit of an uninterrupted power supply (UPS). The DC/DC circuit is a bidirectional DC/DC circuit, and the bidirectional DC/DC circuit is connected between a bus bar and a battery. In a charging mode, the bidirectional DC/DC circuit obtains power from the bus bar and charges the battery; and in a discharging mode, the bidirectional DC/DC circuit obtains power from the battery, and supplies power to the bus bar. In the UPS, the charging circuit and the discharging circuit are integrated into a DC/DC circuit, the DC/DC circuit being a bidirectional DC/DC circuit, and both a charging function and a discharging function are achieved. This allows for a reduction in UPS size, a reduction in cost, and the centralization of key elements, thereby promoting product miniaturization.

摘要： A DC/DC circuit (8) for an uninterruptible power supply, which is a bidirectional DC/DC circuit (8) and connected to a battery (B) and a bus bar. In a mains supply mode, the bidirectional DC/DC circuit (8) draws power from the bus bar and charges the battery (B), and when the mains supply is abnormal, the bidirectional DC/DC circuit (8) works in a state that the battery (B) supplies power to the bus bar. The bidirectional DC/DC circuit (8) includes an isolation transformer. The primary side of the isolation transformer is connected to a push-pull circuit or a half-bridge circuit or a full-bridge circuit, and the secondary side of the isolation transformer is connected to a push-pull circuit or a half-bridge circuit or a full-bridge circuit. The bidirectional DC/DC circuit (8) performs turn ratio switching by selecting the taps of the primary side or the secondary side of the isolation transformer for charging and discharging voltage regulation. The DC/DC circuit for an uninterruptible power supply makes the UPS system simpler and at the same time reduces the system costs.
