Beschreibung
Zusammenfassung:	A driving apparatus of a compressor and a control method thereof are provided to reduce electromagnetic noise generated in driving the compressor by varying the carrier frequency according to the duty ratio of the PWM signal. A driving apparatus of a compressor(140) comprises a motor(143). The rpm of the motor is detected, and a operation duty ratio to make the motor rpm reach the target rpm is calculated. One of carrier frequencies is selected based on the operation duty ratio of the motor, and the motor is operated using the selected carrier frequency.
