Abstract :
This paper presents different schemes of state space vector pulse width modulation (PWM) for three-leg voltage source inverter. The analysis is performed with respect to switching losses and total harmonic distortion. Matlab /simulink programs are derived to illustrate the switching pattern for different schemes of space vector modulation (SVM). They are used afterwards to calculate harmonic values and total harmonic distortion (THD).Besides, the pulse modulation indices (reference signal / carrier signal) for different schemes are set as basis of comparison. The simulation programs are then applied on different types of loads and results are presented.
