並列運転形無停電電源装置。 It has a bidirectional inverter that has a function of converting commercial AC power into DC to charge a storage battery, and a function of converting the DC power of the storage battery to AC to supply AC power to a load, and connects it to a commercial power source. In the continuous commercial parallel operation type uninterruptible power supply device that constantly operates in parallel with the bidirectional inverter, the AC switch that disconnects the commercial power supply line in the event of a power outage is composed of thyristors connected in antiparallel, and the commercial AC is either positive or negative. A function that detects whether it is a half cycle and sends a gate signal that makes each thyristor conductive every positive and negative half cycle based on the detection signal, and a function that detects a power failure and makes it conductive depending on the detection signal. What is claimed is: 1. A continuous commercial parallel operation type uninterruptible power supply device, characterized in that it is equipped with a control circuit having a function of cutting off a gate signal of a thyristor.
