Title: On continuous control of PWM inverters in the overmodulation range including the six-step mode

Abstract

The power output and the dynamic performance of PWM controlled ac drives can be improved by increasing the inverter output voltage through overmodulation. Two different solutions are proposed to increase the output voltage in a continuously controllable fashion up to the maximum possible value, which is reached in the six-step mode. The solutions differ in their respective approach. A space vector strategy is used for high-dynamic performance high-switching frequency drives, while a field-oriented PWM method applies for low switching frequency high-power inverters. The methods are described and analyzed and the experimental results are presented.
