Average Current-Mode Control of DC-DC Power Converters

An authoritative one-stop guide to the analysis, design, development, and control of a wide variety of power converter systemsAverage Current-Mode Control of DC-DC Power Converters provides comprehensive and up-to-date information about average current-mode control (ACMC) of pulse-width modulated (PWM) dc-dc converters. This invaluable one-stop resource covers both fundamental and state-of-the-art techniques in current-mode control of power electronic converters--featuring novel small-signal models of advanced converter topologies with multiple switching elements and previously unpublished coverage of time domain analysis of control circuits.The authors employ a systematic theoretical framework supported by step-by-step derivations, design procedures for measuring transfer functions, challenging end-of-chapter problems, easy-to-follow diagrams and illustrations, numerous examples for different power supply specifications, and practical tips for developing power-stage small-signal models using circuit-averaging techniques. The text addresses all essential aspects of modelling, design, analysis, and simulation of average current-mode control of basic power converter topologies such as buck, boost, and buck-boost converters in continuous-conduction mode (CCM)converter topologies, as well as more advanced converters such as fly back, impedance-source, and dual-SEPIC converters. Bridging the gap between fundamental modelling methods and their application in a variety of switched-mode power supplies, this book:* Discusses the development of small-signal models and transfer functions related to the inner current and outer voltage loops* Analyzes inner current loops with average current-mode control and describes their dynamic characteristics* Presents dynamic properties of the poles and zeros, time-domain responses of the control circuits, and comparison of relevant modelling techniques* Contains a detailed chapter on the analysis and design of control circuits in time-domain and frequency-domain* Provides techniques required to produce professional MATLAB plots and schematics for circuit simulations, including example MATLAB codes for the complete design of PWM buck and boost DC-DC converters* Includes appendices of the basics of fundamental circuits, MATLAB programming, circuit simulation tools, and standard values of passive componentsAverage Current-Mode Control of DC-DC Power Converters is a must-have reference and guide for researchers, advanced graduate students, instructors in power electronics, and for practicing engineers specializing in advanced circuit modelling methods for various converters at different operating conditions.
