A method for driving a converter that converts DC voltage to AC voltage. A voltage conversion circuit has first input terminals and first output terminals insulated from the first input terminals. A filter circuit has second input terminals and second output terminals. A first switch circuit connects the first output and second input terminals. A second switch circuit connects the first switch circuit and the second input terminals. The method includes supplying the first input terminals with DC voltage, converting the DC voltage to AC voltage and supplying the converted voltage to the first output terminals, supplying the second input terminals with the converted voltage, stopping the supply of the converted voltage, and maintaining the first switch circuit or the second switch circuit in an activated state to output AC voltage from the second output terminals of the filter circuit.
