A power converter is an electromechanical or electrical device that converts electrical energy from one form to a desired form. The power converter regulates the power supplied to the resistor through the use of a parallel DC-DC chopper and an unregulated rectifier. It regulates the power flow from an AC supply to the motor by properly controlling power semiconductor switches. The goal of power converter design is to increase efficiency. Controlling the power converters is crucial for ensuring the standards and requirements of the desired purpose. This book aims to shed light on some of the unexplored aspects of power convertors and the recent researches on them. It consists of contributions made by international experts. Students, researchers, experts and all associated with the design and control of power converters will benefit alike from this book.
