Abstract: A method for measuring an offset of a resolver is arranged so as to frequently measure and correct the offset of the resolver by actively performing zero current control of a motor. The method includes steps of: determining whether a torque command value of the motor and a magnetic flux value or reverse magnetic flux value of the motor respectively fall within a first range and a second range, which have been set in advance; controlling the motor to perform zero current control for a preset time period when the torque command value of the motor falls within the first range and the magnetic flux value or reverse magnetic flux value of the motor falls within the second range; and measuring the offset of the resolver for the preset time period.

Abstract: An apparatus for controlling an inverter driving a motor is provided. The apparatus includes a current controller that generates a voltage instruction for causing a current detection value, obtained by measuring a current provided from an inverter to a motor, to correspond to a current instruction for driving the motor. A voltage modulator generates a pulse width modulation signal for controlling on/off states of switching devices in the inverter at a predetermined switching frequency based on the voltage instruction. A frequency determiner determines the switching frequency based on driving information of the motor, determines a plurality of synchronization frequencies based on a speed of the motor, and randomly selects and determines one of the plurality of synchronization frequencies as the switching frequency.
