Abstract

This paper describes a three-phase step-down AC voltage regulator using AC chopper and auxiliary transformer which is series connected with main input. It has many advantages such as fast voltage control, high efficiency and low THD. The operation principle and PWM method of the proposed regulator are described. Experimental results show that it can be used as step-down AC voltage regulator for power saving purpose very efficiently.
