Abstract
A system for controlling an inverter may include a motor; then inverter including a plurality of switching elements turned on/off by a pulse width modulation signal, converting DC power into AC power according to on/off of the plurality of switching elements and providing the AC power to the motor; a current sensor for detecting and outputting a current provided to the motor; a rotation angle sensor for detecting and outputting a rotor angle of the motor; and a controller for performing duty determination control for determining a duty of the pulse width modulation signal on the basis of values detected by the current sensor and the rotation angle sensor and a torque command of the motor.
