Abstract
In this paper, a new voltage modulation technique named \"unified pulsewidth modulation (PWM)\" is described for high-performance voltage generation in a three-phase voltage-fed inverter. By considering the operation of the inverter, a simple but useful concept named \"effective time\" can be established and, by fully employing this concept, a new voltage modulation technique is presented with a detailed explanation and actual test results. The results show that various carrier-based PWM schemes can be implemented with reduced computational burden and a seamless change from one modulation scheme to another is possible.Keywords
