The application of solid-state electronics for controlling and converting electric power is referred to as power electronics. Modern power electronics systems use semiconductor switching devices such as diodes, thyristors and power transistors to perform the conversion. The power conversion systems can be classified into various categories such as AC to DC, DC to AC, DC to DC and AC to AC. AC to DC converter is found in many consumer electronic devices such as television sets, battery chargers and personal computers. DC to AC converters are known as power inverters. They are used in numerous devices such as adjustable speed drives, uninterruptible power supplies and flexible AC transmission systems. This book elucidates the concepts and innovative models around prospective developments with respect to modern power electronics. Different approaches, evaluations and principles related to this field have been included herein. Coherent flow of topics, student-friendly language and extensive use of examples make this book an invaluable source of knowledge.
