Abstract
In the present paper experimental and simulation results of three phase voltage source inverter (3P-VSI) controlled by the strategy called discontinuous pulse width modulation technique (DPWM_3) corresponding to four saturation of 30° are presented. This technique is proposed to overcome the disadvantages of the space vector pulse width modulation (SVPWM) mainly high modulation frequency and increased inverter switching losses. This control strategy is a simple and an easy technique generating the same switching pattern as space vector modulation with less switching losses and reduced total harmonic distortion. The main motivation of the present paper is that the DPWM is not largely and deeply investigated and can present a serious alternative to other PWM techniques. The obtained results have showed that with DPWM technique, switching losses and total harmonic distortion (THD) are reduced. Furthermore, the implementations of this technique in a dSPACE (DS1104) controller is discussed and analyzed
