An object is to provide an inverter device overvoltage protection method that can appropriately protect the inverter device 2 from an overvoltage condition. When a direct current Voltage rises, and a direct current Voltage detection value detected by a direct current voltage detector 52 exceeds a second direct current voltage level, a protective circuit 50 carries out a stop of the operation of an inverter device 2 by outputting an inhibit signal to a gate drive circuit 51, but it is determined at this time that the rise of the direct current voltage is temporary, and no error output signal is output from an error signal generator 55 to the exterior of the inverter device 2. Meanwhile, in the event that the direct current voltage rises further while the inverter device 2 is temporarily stopped, and the direct current voltage detection value exceeds a first direct current Voltage level, it is determined that protection of the inverter device 2 is necessary, and an error output signal is output to the exterior of the inverter device 2.
