Abstract

The invention provides a boost module of an uninterrupted power system. The boost module can be electrically connected to an inverter and a battery. The boost module comprises a first inductor, a first capacitor, a second capacitor, a first switch unit, a second switch unit and a third switch unit. Under a commercial power mode or a battery mode, the uninterrupted power system controls each switchunit to enable the first inductor to be changed by the voltage input by a voltage input end, and the voltage output by the first inductor is received by the first capacitor or the second capacitor. Through control of each switch, design of the original circuit is simplified.

Description

technical field [0001] The invention relates to a boosting module for an uninterruptible power system, in particular to a boosting module for an uninterruptible power system that can effectively simplify circuits. Background technique [0002] In the uninterruptible power system (UPS), because the storage of the battery provides reliable electric energy, it ensures the stable operation of the uninterrupted system. In the past, most uninterruptible power systems (UPS) used lead-acid batteries, and boosted the battery voltage through a push-pull converter (Push-Pull), and then output the boosted voltage to the inverter (inverter). [0003] However, the battery of the known uninterruptible power system must use a push-pull converter to boost the voltage, which will increase the overall circuit complexity, and the uninterruptible power system must also add extra volume to match the circuit with the push-pull converter. Setting, and the battery output voltage through the push-pu...
