This paper presents a carrier-based unbalanced pulsewidth-modulated method for a two-phase four-leg voltage source inverter (VSI) and its realization for an unsymmetrical two-phase induction motor. A modulation strategy is developed to synthesize unbalanced two-phase output voltage waveforms based on the unipolar modulation technique with open-loop V/f… (More)

Voltage sag compensation using two three-phase voltage-fed PWM converters is presented. This is new approach to mitigate the voltage sags without using special energy storage devices or power transformers. In the normal incident, the load is fed the power from utility supply via main static transfer switch. When voltage sag is occurred, the main static… (More)
