Zusammenfassung:	PROBLEM TO BE SOLVED: To realize reduction of drive loss of a current drive element by supplying an adequate drive current to a current drive element. SOLUTION: A control signal generating circuit 20 generates a voltage waveform consisting of two kinds of pulses and then outputs this generated voltage waveform to a drive circuit 10 as the first and second control signals. The drive circuit 10 generates a 3-split pseudo sine wave current based on the first and second control signals inputted from the control signal generating circuit 20. The drive circuit 10 supplies the 3-split pseudo sine wave current as a drive current to a current drive element 40.
