Abstract – Purpose of this paper is to simulate and study an “AC-AC Converter” with improved input power quality and its output parameters. Reduced Input current harmonics and enhanced input power factor are met by involving active front end converter.  Output stability, repeatability and its real time control in dynamic situation were prime parameters to be designed. Power topology includes double power conversion, viz. AC to DC and DC to AC. A PWM control method is selected for both power conversions. In this paper, a full focus is applied to explain my design work related to simulation and study of an AC-AC converter topology along with a principle goal of improved power quality management. Content of this document is enriched by the way of adding suitably tabulations, graphics and schematics for the reader to easily digest.
