  • Device of uninterruptible power supply
    Publication number: 20030076696
    Abstract: The present invention relates to a three-phase uninterruptible power supply for receiving an input alternating current (AC) voltage and providing an output AC voltage. The three-phase uninterruptible power supply includes a rectifying circuit for receiving the input AC voltage and outputting a direct current (DC) voltage, an inverter for receiving the DC voltage and outputting the output AC voltage, a couple of capacitors respectively electrically connected with the rectifying circuit and the inverter via a first bus and a second bus, and a neutral ground electrically connected to the couple of capacitors to link the DC voltage and the output AC voltage for grounding.
