Summary

The most comprehensive book on power supply design--fully updated with the latest techniquesSwitchmode Power Supply Handbook, Third Editionis a thoroughly overhauled edition of the industry-leading, practical guide for power supply designers. The book now addresses the new design techniques required for powering the small, high-performance electronic devices in use today. Based on the author's 45 years of experience, the book is filled with real-world solutions and avoids unnecessarily complicated mathematical derivations and theory. It provides practical techniques in power supply design and clear, step-by-step approaches to component decisions. The many worked examples included are based on actual working prototypes. In-depth topics such as electromagnetic interference, line filters, fuse selection, and active power factor correction are covered.Switchmode Power Supply Handbook, Third Editionfeatures: New coverage of the latest techniques for powering modern electronics Highly visual layout with proven design examples throughout Supporting mathematical derivations in appendix form for easy access Coverage of the design of high-frequency transformers and chokes Worked problems at the end of each chapterComplete coverage of power supply design: Functions and Requirements Common to Most Direct-Off-Line; Switchmode Power Supplies; Common Requirements; AC Powerline Surge Protection; Electromagnetic Interference (EMI) in Switchmode Power Supplies; Faraday Screens; Fuse Selection; Line Rectification and Capacitor Input Filters for "Direct Off-Line" Switchmode Power Supplies; Inrush Control; Start-Up Methods; Soft Start and Low-Voltage Inhibit; Turn-On Voltage Overshoot Prevention; Overvoltage Protection; Undervoltage Protection; Overload Protection; Foldback (Reentrant) Output Current Limiting; Base Drive Requirements for High-Voltage Bipolar Transistors; Proportional Drive Circuits for Bipolar Transistors; Antisaturation Techniques for High-Voltage Transistors; Snubber Networks; Cross Conduction; Output Filters; Power Failure Warning Circuits; Centering (Adjustment to Center) of Auxiliary Output Voltages on Multiple-Output Converters; Auxiliary Supply Systems; Parallel Operation of Voltage: Stabilized Power Supplies; Design: Theory and Practice; Multiple-Output Flyback Switchmode Power Supplies; Flyback Transformer Design; Reducing Transistor Switching Stress; Selecting Power Components for Flyback Converter; Self-Oscillating Direct-Off-Line Flyback Converters; Applying Current-Mode Control to Flyback Converters; Direct-Off-Line Single-Ended Forward Converters; Transformer Design for Forward Converters; Diagonal Half-Bridge Forward Converters; Transformer Design for Diagonal Half-Bridge Forward Converters; Half-Bridge Push-Pull Duty-Ratio-Controlled Converters; Bridge Converters; Low-Powered Self-Oscillating Auxiliary Converters; Single-Transformer Two-Transistor Self-Oscillating Converters; Two-Transformer Self-Oscillating Converters; The DC-to-DC Transformer Concept; Multiple-Output Compound Regulating Systems; DC-to-DC Switching Regulators; High-Frequency Saturable Reactor Power Regulators; Constant-Current Power Supplies; Variable Linear Power Supplies; Switchmode Variable Power Supplies; Switchmode Variable Power Supply Transformer Design; Applied Design; Inductors and Chokes in Switchmode Supplies; High-Current Chokes Using Iron Powder Chores; Choke Design Using Iron Powder Toroidal Cores; Switchmode Transformer Design: General Principles; Optimum 150-W Transformer Design Example Using Nomograms; Transformer Staircase Saturation; Flux Doubling; Stability and Control-Loop Compensation in SMPS; The Right-Half-Plane Zero; Current-Mode Control; Optocouplers; Ripple Current Ratings for Electrolytic Capacitors in Switchmode Power Supplies; Noninductive Current Shunts; Current Transformers; Current Probes for Measurement Purposes; Thermal Management
