책소개

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.
