Switching Power Supply Design

by Pressman

Using this book as a guide,Pressman promises,even a novice can immediately design a complete switching power supply circuit. No other book has such complete instruction in one volume. Using a tutorial,how-to approach,Pressman covers every aspect of this new technology,including circuit and transformer design,using higher switching frequencies,new topologies,and integrated PWM chips. For this latest edition,Pressman has added in-depth discussion of power factor correction,high-frequency ballasts for fluorescent lamps,and low-input voltage power supplies for laptop computers. A practical guide to state-of-the-art power supply design Nowhere else can you find,in one book,all the information you need to design a switching power supply. And no other book on the subject is as practical,yet mathematically sufficient,without being unnecessarily academic. Using a tutorial,how-to-do-it approach,Pressman first explains basic principles and why thigs are done as they are. With a knowledge of basic principles,the engineer can easily cope with new design requirements and evaluate alternative design decisions. The topics covered represent all those areas where a design decision has to be made in commencing a new design. These Topology Descriptions — A quantitative description of the roughly 15 commonly used topologies. Maximum current and voltage stress on power transistors for specified input voltage-output powers are described. The discussion permits selection of an optimum topology for the specified input-output voltages,output powers,and the selection of the power transistors; High-Frequency Magnetics Fundamentals—Ferrite core hysteresis,coil skin effect,andproximity effect losses; Transformer Design—Derivation of equation for transformer core selection for available output power as a function of frequency,flux density,iron and bobbin area,and topology; novel charts derived from the equations,permitting core selection at a glance; core,coil,total transformer loss,and temperature rise calculations; transformer design examples in major topologies; DC Current Biased Inductor Design — Design of inductors carrying DC bias currents using ferrite,MPP,Koolmu,and powered iron cores; Magnetic Amplifier,Snubber Designs,and Resonant Converters; Feedbak Look Stabilization; Critical Polaroid Waveforms in Major Topologies. This second edition adds chapters on the current hottest topics in the field; power factor corrections,high-frequency ballsts for flourescent lamps,and low-input voltage power supplies for laptop computers.
