<p>An inverter device includes a switch circuit (5) configured by series-connecting two N-channel semiconductor switching elements (6a, 6b) in opposite directions so that the switch circuit (5) makes or breaks electrical connection between a DC power supply (4) and an inverter circuit (1) and a control circuit (35) carrying out a protecting operation in which when the control circuit (35) output a control signal to control switching of the inverter circuit (1) and an operating condition is met, 1 the control circuit (35) stops output of the control signal to turn off all switching elements (6a, 6b) configuring the inverter circuit (1) and the switch circuit (5). In the protecting operation, the switch circuit (5) is turned off after output of the control signal has been stopped.</p> |
