English Abstract

This paper presents a modified space vector pulse width modulation to drive permanent synchronous motor, the switching pattern of modified space vector pulse width modulation (MSVPWM), with certain notches, in the switching pattern of conventional type, are eliminated.

These notches at relatively high modulation index have small width compared with switching period.

The modified strategy has many features, such as increasing the utilization of dc input voltage and therefore higher output voltage, reducing the stress on power switches, and reducing switching power losses.

The percentage reduction in the number of pulses for each switch device is about 33% of total number of switching pattern.

This is due to the nature of space vector pulse width modulation.

The proposed approach is analyzed and simulated, using Matlab Simulink .

The obtained results prove that the proposed strategy has low power switching losses, and higher fundamental range and good quality of output voltage waveform compared with conventional space vector.

Practical results have been obtained which validate the theoretical and simulation approaches.
