Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a method and device of controlling a compact and highly-efficient oscillation type compressor, without using a DC/DC converter. SOLUTION: A fundamental period and a PWM signal are generated by a microprocessor unit (MPU) and a full bridge type inverter is operated to drive an electromagnetic coil of the oscillation type compressor. Variation of input voltage of the inverter is controlled by means of a PWM pulse width, and the fundamental period is corrected based on detection of a zero cross point of the voltage induced in the electromagnetic coil.
