ータ装置。 In an inverter device equipped with a switch for switching between inverter output and bypass, when the inverter becomes overloaded, it consists of a thyristor switch and a magnet switch to reduce the inverter output voltage and simultaneously switch between inverter output and bypass. A signal is given to the switch to switch from the inverter to the bypass without momentary interruption, and when the overload is removed, after confirming that the overload has been removed, there is a means of automatically switching from the bypass to the inverter without interruption. An inverter device comprising:
