Zusammenfassung:	PROBLEM TO BE SOLVED: To generate an output voltage formed from a sinewave even when an LC circuit is connected with the subsequent stage of a main circuit.SOLUTION: The inverter control circuit 1 includes: a quantizer 7 that generates a switching signal for changing over a switch of a main circuit that converts a DC voltage into an AC voltage, and a filter circuit 6 that generates a predetermined transfer characteristic signal, using a signal correlating to an output voltage of an LC filter for smoothing an AC voltage and a command signal corresponding to a target value of an output voltage of the main circuit. The quantizer quantifies an output signal of the filter circuit and generates a change-over signal.
