とする無停電電源装置のバイパス切換回路。[Claims for Utility Model Registration] An electromagnetic switching device that switches power supply to a load from an inverter device to a bypass power source; a control device that is connected to a control power source and that detects a failure of the inverter device and outputs a detection signal; A bypass switching command generating section is provided, which includes a switching element that is turned on by a signal, a relay connected in series to this switching element, and a relay contact that outputs a bypass switching command to the electromagnetic switching device when the relay is energized. In a bypass switching circuit for an uninterruptible power supply, a capacitor is connected in parallel to the series circuit of the relay and the switching element, and the capacitor is connected in parallel to the series circuit of the relay and the switching element so that the charge in the capacitor flows to the relay and the switching element in the event of a failure of the control power supply. A bypass switching circuit for an uninterruptible power supply, characterized in that a diode is connected between a capacitor and a control power source, and the relay contact is connected to the bypass power source.
