Abstract

See full text

An apparatus for controlling an inverter for driving a motor includes a processor which includes: a current processor for generating a voltage command for causing a current detection value obtained by measuring a current supplied from the inverter to the motor to follow a current command for driving the motor; a voltage modulator for generating a pulse width modulation signal for controlling on and off states of switching elements in the inverter with a predetermined switching frequency based on the voltage command; and a frequency determining processor for setting a frequency change range within which the switching frequency will be randomly changed and randomly determining the switching frequency within the frequency change range when a random pulse width modulation method is applied to control of the inverter.
