When supply of electric power to an inverter using a normally-ON switching element is abnormally stopped, a flow of a current to the switching element of the inverter is reduced. An inverter circuit includes an inverter having at least one arm including two normally-ON switching elements connected in series between two lines to which a voltage of a power supply is applied, a smoothing capacitor connected between the two lines at a position between the power supply and the inverter, and a normally-OFF relay connected into the first line out of the two lines at a position between the smoothing capacitor and the inverter.
