Abstract
The power output and the dynamic performance of pulse width modulation (PWM)-controlled AC motor 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 approach. A space vector strategy is used for high dynamics performance high switching frequency drives, while a field-oriented PWM method is used for low switching frequency high power inverters. The methods are described and analyzed, and experimental results are presented.Keywords
