چکیده مقاله:
This paper presents the performance of multi-phase voltage source inverter (VSI) with simple PWM switching techniques, namely the harmonic injection and offset injection method. The techniquediscussed in this paper is easy to implement and avoid complicated controlling algorithm adapted inSVPWM technique. The generalized switching techniques are proposed in this paper. A generalized algorithm suitable for odd number of phases is developed in Matlab/Simulink environment anddiscussed in detail for both the switching methods. The performance of the 5, 7 and 9-phase VSI isstudied with the above-said switching methods. The results of the simulation are presented for different modulation indices and a comparison in terms of fundamental voltage and THD identifies the better scheme suitable for multi-phase inverter fed drives
