Abstract
An apparatus for controlling an inverter for driving a motor including a processor which includes: a current processor configured to generate a voltage command for allowing a current detection value, generated by measuring a current provided from an inverter to a motor, to follow a current command for driving the motor; a voltage modulator configured to generate a pulse width modulation signal for controlling on and off states of a switching element within the inverter with a predetermined switching frequency based on the voltage command; and a frequency determining processor configured to randomly change the switching frequency based on driving information of the motor.
