Abstract :
Operating voltage pulse width modulated (PWM) inverters in the overmodulation region extends their voltage and power range and improves their dynamic performance. This paper is a contribution to the extension of the operating range of the classification algorithm for the implementation of space vector modulation (SVM) in the pulse dropping region. Two different schemes are proposed to continuously increase the output voltage up to the maximum attainable value in a controllable manner. Mathematical analysis and experimental results verify the validity of the proposed schemes
