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.82 pagesenBRAC University thesis are protected by copyright.
