Performance Analysis of SPWM and SVPWM Inverters Fed Induction Motor

This paper presents the analysis of the sinusoidal pulse width modulation (SPWM) and space-vector modulation (SVPWM). The analysis involves the relationship between modulation signals and space vectors and the switching patterns of spacevector modulation and the trigger of power electronic device .All the relationships provides a bidirectional bridge for the transformation between sinusoidal PWM modulators and space-vector modulation modulators. It is noted that all the drawn conclusions are independent of the load type. Nevertheless, the implementations of both SPWM and SVPWM circuits are carried out using three phase induction motor as a load.
