構成したことを特徴とする無停電電源装置。[Claims for Utility Model Registration] AC power from a commercial power source is converted into DC power by a forward converter, and this DC power is supplied to an inverse converter through a DC filter, and when the commercial power supply is out of service, the power is supplied from the battery. In an uninterruptible power supply device in which DC power is applied to an inverse conversion unit and the battery is charged by a charging unit, a chopper is provided on the output side of the DC filter, and the output voltage of the chopper is smoothed to supply DC power to the battery. An uninterruptible power supply device characterized in that the charging section is constituted by a reactor and a flywheel diode that supply the voltage, and a control section that controls on/off of the chopper so as to match the battery voltage.
