This text is intended to be of use to advanced undergraduates, offering a clear introduction to the field of power electronics. An introductory chapter describes the practical uses of semiconductor devices to convert and control electrical power. This text emphasizes real-world applications, with examples taken from industrial environments in which the author has had experience. This approach is supplemented with over 250 illustrations, numerous sample problems, and many end-of-chapter exercises, all designed to illuminate basic underlying principles. This text also features good organization, providing enough background information to flow gradually from simple topics to advanced ones, and then elaborates on these topics to enhance the book's use as a reference tool for graduates and professionals. Chapters cover topics such as: power quality and vector control; power semiconductor devices; multiphase choppers and PWM inverters; and adjustable speed AC and DC motor drives.
