充電したことを特徴とする予備充電装置。There is a forward converter that converts AC input power from a commercial frequency power source into DC power and is composed of a diode rectifier, a DC filter circuit that consists of a DC reactor and a smoothing capacitor, and a reverse converter that converts DC power back to AC power. A battery charger consisting of a converter, a thyristor rectifier that rectifies commercial frequency AC power and charges the battery in a floating manner and equally, and a DC circuit breaker that supplies the battery's DC power to the reverse converter in the event of an abnormality in the commercial frequency power supply. In an uninterruptible power supply device having a DC switch circuit composed of a DC switch circuit and a DC switch, the smoothing capacitor is precharged at the time of starting the device,
A preliminary charging device formed by connecting a thyrisk switch and a current limiting resistor in series is connected in parallel between the terminals of the DC breaker,
A preliminary charging device characterized in that the smoothing capacitor described above is preliminary charged through a loop of a battery charger, a preliminary charging device, and a DC switch circuit.
