In this paper, computer simulation of a three-phase synchronous motor drive is described. This drive/system is supplied with a new type of pulse-width modulated voltage source inverter (PWM VSI) whose amplitude of the first harmonic, compared to a conventional sinusoidal PWM VSI, is increased by about 17% and whose amplitude of higher harmonics is also reduced inversely proportional to their orders. This system has low torque pulsations and approximately has a unity power factor at operation below the base speed. In addition, it has a dynamic performance very close to DC drives with quick dynamic response.
