Choi (electrical engineering and computer science, Kyungpook National U., Korea) provides a textbook for undergraduate students beginning the study of power electronics, supplementing textbooks with a more detailed treatment of pulsewidth modulated conversion of direct current to direct current electricity. It can also serve as a reference for more advanced students and for engineers engaged in modeling, analyzing and controlling converters. Among the topics are power stage components, buck converter, power stage transfer functions, closed-loop performance and feedback compensation, and current mode control. Annotation ©2013 Book News, Inc., Portland, OR (booknews.com)

This book provides engineers in the power electronics field with complete guidance to pulsewidth modulated (PWM) DC-to-DC power converters. It explains the circuit and operation of PWM DC-to-DC converters and their dynamic characteristics along with in-depth discussion of the current mode control scheme for PWM DC-to-DC converters. Topics include the functional basics, dynamic modeling and analysis, compensation design, and applications of current mode control. Fully tested problems and simulation examples are included, as well as downloadable lecture slides and ready-to-run PSpice programs.
