Power Electronics: Principles and Applications

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.
