る無停電電源装置。 A rectifier consisting of a diode that rectifies AC power and converts it into DC power. An inverter that reversely converts DC power and converts it into AC power. A storage battery that supplies DC power to the inverter when AC power is lost; a DC switch that switches to the storage battery power source; and a DC switch that charges the storage battery. An uninterruptible power supply consisting of a rectifier with a separate voltage control function that rectifies AC power to convert it into DC power, and a UPS switch that switches to the direct bypass AC power supply to continue supplying AC power in the event of an inverter failure. In the device, a means is provided to charge the smoothing capacitor on the DC side through the flywheel diode of the self-extinguishing semiconductor element in the inverter section by controlling the firing phase of the control rectifier of the UPS switch at startup. Features an uninterruptible power supply.
