Abstract
An apparatus for controlling an inverter to drive a motor includes: a current control processor generating a voltage command for generating d/q axis current detection values, which are obtained by measuring current supplied to the motor, to follow a d/q axis current command for driving the motor, the current control processor converting the voltage command, which is sampled according to a sampling frequency generated based on a voltage vector phase of the voltage command, into a voltage vector corresponding to a point on each vertex and each side of a hexagon in a voltage vector diagram to apply a resulting value to the inverter driving the motor; and a sample frequency computing processor computing the sampling frequency based on the voltage vector phase of the voltage command and a reference number of sampling times during one rotation period of the motor.
