Abstract

The invention relates to a UPS module and a UPS system. The UPS module comprises a DC / DC unit, and a PFC unit, an inversion unit and a charger, wherein the PFC unit, the inversion unit and the charger are connected in turn. The PFC unit comprises a rectification circuit and a chopper circuit, wherein the rectification circuit and the chopper circuit are connected. The PFC unit is characterized in that, when the AC commercial power is abnormal, a first leg of the chopper circuit transforms an output voltage of a storage battery into a first DC voltage, and outputs to a first input end of the inversion unit, the DC / DC unit transforms the output voltage of the storage battery to a second DC voltage, and outputs to a second input end of the inversion unit, and the inversion unit inverts the first DC voltage and a second DC unit into an AC voltage. The execution of the technology scheme of the invention raises efficiency and saves space and cost.

Description

technical field [0001] The present invention relates to power electronic technology, and more specifically, relates to a UPS module and a UPS system. Background technique [0002] UPS (Uninterruptible Power Supply, uninterruptible power supply) is widely used in many industries such as electric power, telecommunications, finance, government, manufacturing, etc. It can guarantee to continue working for a period of time after a power outage, so that users will not affect their work or lose data due to power outages. It can also eliminate "power pollution" such as power surges on the mains, momentary high voltage, momentary low voltage, wire noise and frequency deviation. [0003] figure 1 It is a circuit diagram of a UPS module in the prior art. The UPS module is used for charging and discharging the battery, and includes a PFC unit 100, an inverter unit 200, a charger 300 and a DC / DC unit 400, wherein the PFC unit 100 includes rectifier circuit and chopper circuit. When th...
