Abstract

This paper investigates the equivalence of the two popular approaches to Pulsewidth Modulation (PWM) in induction motor drives, namely the triangle-comparison approach and the space vector approach. It brings out the conditions wherein they are equivalent, and wherein they are not. It shows that the space vector approach is more general, and offers more degrees of freedom, compared to the triangle-comparison approach. Even a limited exploitation of these flexibilities has been reported to have improved the drive performance significantly. This gives adequate motivation to exploit these flexibilities further.
