Design of a single phase AC-AC converter

Abstract

An AC-AC voltage controller is a converter which controls the voltage, current and average power delivered to an AC load from an AC source. They are used in practical circuits like light dimmer circuits, speed controls of induction motors, traction motors control etc. In our thesis we will analyze the performance of a single-phase AC-AC circuit with emphasis on the output harmonic content and utilization of input voltage. This converter can convert from a fixed AC input voltage into variable AC output voltage with desired frequency.
