A method of pulse width modulation (PWM) generation for a converter of an electric or hybrid vehicle electric machine. The converter is operated with phase shifts with a duty cycle associated with a phase shift, and the converter provides voltage to a transformer of the electric machine. The method of pulse width modulation generation includes operating the converter with requests of duty cycle change, with a subdivision period being defined between two requests of duty cycle change. Half of the duty cycle is applied at the start of said subdivision period and half of the duty cycle is applied at the end of said subdivision period.
