切換え装置。 The power supplied to the load is switched between the bypass power supply and the constant frequency constant voltage device via a switch,
In an uninterruptible power supply that switches without momentary interruption while controlling an AC switch connected between the bypass power supply and the load during this switching, a brittle connection is made in parallel with the load side end of the changeover switch and the connection end of the constant frequency voltage regulator. When a series circuit of a rectifier, a reactor, and a resistor is connected, and a control power source is connected to the AC input side of the rectifier, a detector that detects the presence or absence of a DC current flowing in the series circuit, and this detection 1. A switching device for an uninterruptible power supply, comprising: a gate control circuit for controlling the AC switch depending on the presence or absence of an output signal from the switch.
