Power Electronics; Principles and Applications guides the reader through the circuit analysis techniques in the design, analysis and fabrication of power electronics for consumer, and commercial applications as well as those unique to industrial manufacturing. Included are composite high-voltage amplifiers, power op amps, linear audio power ICs, MOSFETs used in class AB amplifiers and in power switches, switching power supplies, thyristors and thyristor control circuits. Ideal for use in ABET-accredited engineering technology programs, the book adds to the classical industrial power control a rare mix of electronics designed to deliver power to consumer and commercial loads such as audio systems, and the management of power for the explosion of hand-held devices. How a power circuit is built is as critical as the parts that are selected. Both protoboard and printed circuit board layout principles are explained with detailed, step-by-step illustrations, photographs and lots of lab practice. Microprocessors are pervasive; in garage door openers, microwave oven, refrigerators, faxes, printers, copiers, and many toys. Power electronics are needed to follow their commands, delivering hundreds of milliamps to tens of amps to the motors, valves, heaters and lights that we use. A variety of low and high side switches, switch drivers and H bridges are illustrated. Buck, boost, flyback and line-powered switching power supplies are explained, design techniques and special purpose IC explored in detail, and practical laboratory exercises provided. Additional chapters feature circuit design simulations and lab exercises that offer practice in the design, analysis, fabrication and testing of classical industrial thyristor-based conversion and motor drive circuits. Salient Features Comprehensive coverage includes audio and linear IC and discrete power amplifiers as well as the traditional industrial power interfaces. Coverage of breadboarding and printed circuit board layout techniques reveal the secrets of building a board that works correctly the first time. Switching power supplies - the predominant way of managing power in today's increasingly unplugged consumer electronics - are addressed in detail. Multisim and OrCAD's Pspice simulations are used in examples and problems throughout the text, enabling the reader to uncover marginal performance and design flaws before a prototype test results in sudden and spectacular self-destruction. Over 100 fully worked examples (many with simulations) are each followed with a practice-exploration, allowing the reader to test and verify their understanding of the principle. Hundreds of students have tested the laboratory exercises at the end of each chapter. They clearly illustrate the principles of power electronics design, fabrication and testing.
