Abstract:
A method of controlling an output voltage of an inverter driving an electric motor may include calculating a current total harmonic distortion (THD) of a current output to the electric motor; comparing the current THD with a reference current THD; determining a pulse width modulation (PWM) method to be changed from a first modulation method that reduces harmonic components of the current output to the electric motor to a second modulation method when the current THD is less than the reference current THD, the PWM method modulating a pulse width of a control pulse signal for controlling the output voltage of the inverter; and/or generating the control pulse signal based on the determined PWM method.
