Abstract
An inverter circuit includes plural pairs of third coils, in which adjacent third coils are serially connected to each other so as to offset AC voltage generated from the paired third coils, one end of the paired third coils being connected to ground. Input terminals of plural diodes are connected to one end of the paired third coils so as to generate the voltage detection value by detecting voltage generated from the paired third coils. A fault detector compares the voltage detection value generated from the diodes with a predetermined threshold value to detect a fault and generates the comparison result.
