Abstract
A new method for PWM in the over-modulation range is proposed. The range of the method, called mode III, covers the range previously covered by modes I and II. It allows extending the maximum modulation index in SVM from 0.906 to 1 where six-step mode is reached. The new method shows a very good linearity and is simpler to apply than the space vector modulation scheme and the voltage reference scheme. A description of the method, its implementation, and simulation and experimental results are presented and discussed.Keywords
