Pulse Width Modulated DC-DC Converters, Softcover reprint of the original 1st ed. 1997

For the first time in power electronics, this comprehensive treatment of switch-mode DC/DC converter designs addresses many analytical closed form equations such as duty cycle prediction, output regulation, output ripple, control loop-gain, and steady state time-domain waveform. Each of these equations are given various topologists and configurations, including forward, flyback, and boost converters. Pulse Width Modulated DC/DC Converters begins with a detailed approach to the quiescent operating locus of a power plant under open-loop. The reader is then led through other supporting circuits once again in the quiescent condition. These exercises result in the close-loop formulations of the subject system, providing designers with the ability to study the sensitivities of a system against disturbances. With the quiescent conditions well established, the book then guides the reader further into the territories of system stability where small signal behaviors are explored. Finally, some important large signal time-domain studies cap the treatment. Some distinctive features of this book include: *detailed coverage of dynamic close-loop converter simulations using only personal computer and modern mathematical software *Steady-state, time-domain analysis based on the concept of continuity of states Voltage-mode and current-mode control techniques and their differences of merits A detailed description on setting up different equations for DC/DC converters'simulation using only PC

This book concentrates on modern switch-mode power supplies and includes scenarios and cases of operations under quiescent (inactive) and active conditions. This is a comprehensive approach the author adopts for each of the three topologies covered : forward, flyback, and boost converters. The book includes many equations and provides real insight into the various uses of DC/DC conversion. The equations found in the book are designed to help engineers predict steady state duty cycles, determine transformer/turn radio, and provide accurate information impacting a variety of analytical and design issues.
