The branch of electronics which seeks to apply solid state electronics for the purpose of controlling and converting electrical power is known as power electronics. There are primarily two areas of applications of power electronics such as switches or amplifiers. Ideally, switches should not dissipate any power while they are open or closed. The current in amplifiers varies continuously depending upon the controlled input. Some of the systems which are based on power electronics are AC/DC converters, DC/AC converters, DC/DC converters and AC/AC converters. Inverters are a type of devices which are used to convert DC to AC. This book discusses the fundamentals as well as modern approaches of power electronics. Those in search of information to further their knowledge will be greatly assisted by it. Coherent flow of topics, student-friendly language and extensive use of examples make this book an invaluable source of knowledge.
