Phase angle analysis for PWM-switched autotransformer voltage-sag compensator

This study proposes a controller for a single- and a three-phase pulse width modulation (PWM) voltage sag compensator. The controller comprises a combination of a new sag detection technique namely phase angle analysis and a PWM voltage controller. The detection technique offers immediate voltage sa...
