。In an uninterruptible power supply device that forwards and reverses converts commercial power to supply power to a load, and also switches to a battery and supplies power to the load when a power outage occurs, an uninterruptible power supply device connected between the output end of the forward converter and the battery. It is characterized by comprising a series circuit consisting of a diode and a step-down chopper circuit, a transformer that detects a power outage or power restoration of the commercial power source, and a control circuit that controls the conduction rate of the chopper circuit based on the detection result of the transformer. DC switch circuit for an uninterruptible power supply.
