An unbalance voltage compensator using a Fast On-Load Tap Changing Regulator

This paper presents a Fast On-Load Tap Changing Regulator used to correct unbalanced voltages. This regulator uses the semi natural commutation in order to improve the response. The proposed topology injects the voltage in only phase in order to balance the three phase system.
