The paper introduces a modified space vector pulse width modulation strategy which has been used to drive and control the speed of permanent magnet synchronous motor. This strategy, compared with relative conventional SVPWM method, has important features. Such features are increasing the utilization of DC link input voltage of the inverter, reducing the stress on power switching devices, and therefore minimizing the switching losses. The proposed approach is analyzed and simulated. Also a complete system model of the permanent magnet synchronous motor (PMSM) drive, using MatLab-Simulink, has been performed. The obtained results, for conventional and modified approaches, have been compared. In order to verify the theoretical results, practical test has been performed which shows that the proposed technique is preferable than the conventional type.
