Book Description
Too much current flowing through an electric circuit can damage the circuit and can create a safety hazard. How much current is "too much current"? That depends on the circuit and its components. For some circuits, 1 ampere would be too much current, while for other circuits 1 ampere would be perfectly acceptable. Circuit protection devices protect electrical equipment by rapidly disconnecting power to components in the event of an abnormal overload conditions resulting from excessive voltages, ground faults, and accidental shorting of a circuit. Two types of circuit protection devices are common; fuses and circuit breakers both operate by opening and interrupting current to the circuit. A fuse or circuit breaker is designed to create an open circuit if too much current flows through it. You can think of it as a switch that automatically turns itself off if the current through it exceeds a certain level. When a fuse is "blown" by having too much current pass through it, the fuse is ruined and must be replaced. On the other hand, when a circuit breaker is "tripped" by excessive current, the circuit breaker can be reset and used again, instead of being discarded. The choice of which to use depends on the specific application, circuit type, its electrical specifications, space available, environmental constraints, and customer preference. In the US, the National Electric Code (NEC) exists to guide electricians in the proper installation of electrical equipment and defines the specific requirements for circuit protection. In Canada the Canadian Electric Code (CEC) exists to provide similar guidance. Other areas of the world have equivalent country or local codes.A proper circuit protection strategy reduces long-term maintenance needs and other costs, and minimizes system downtime. This 3-hr Quick Book provides an overview of circuit protection devices and is based entirely on Naval Education and Training Materials (NAVEDTRA 14175), Electricity and Electronic Training Series; Module-3 and covers Chapter 2 titled “Circuit Protection Devices”. This course is aimed at students, professional engineers, service technicians, energy auditors, operational & maintenance personnel, facility engineers and general audience. At the conclusion of this course, the reader will be able to:• State the reasons why circuit protection is needed.• Define a direct short, an excessive current condition, and an excessive heat condition.• State the way in which circuit protection devices are connected in a circuit.• Identify two types of circuit protection devices and learn their types and characteristics.• List the three time delay ratings of circuit breakers.• Define selective tripping and state why it is used.• Identify the factors used in selecting circuit breakers.• List the methods of checking and the items to check when replacing and/or maintaining fuses and circuit breakers.

Book Description
In the earlier stages of integrated circuit design, analog circuits consisted simply of type 741 operational amplifiers, and digital circuits of 7400-type gates. Today's designers must choose from a much larger and rapidly increasing variety of special integrated circuits marketed by a dynamic and creative industry. Only by a proper selection from this wide range can an economical and competitive solution be found to a given problem. For each individual case the designer must decide which parts of a circuit are best implemented by analog circuitry, which by conventional digital circuitry and which sections could be microprocessor controlled. In order to facilitate this decision for the designer who is not familiar with all these subjects, we have arranged the book so as to group the different circuits according to their field of application. Each chapter is thus written to stand on its own, with a minimum of cross-references. To enable the reader to proceed quickly from an idea to a working circuit, we discuss, for a large variety of problems, typical solutions, the applicability of which has been proved by thorough experimental investigation. Our thanks are here due to Prof. Dr. D. Seitzer for the provision of excellent laboratory facilities. The subject is extensive and the material presented has had to be limited. For this reason, we have omitted elementary circuit design, so that the book addresses the advanced student who has some back ground in electronics, and the practising engineer and scientist.

Book Description
Electromagnetic pulses from nuclear weapons, lightning, and electrostatic discharge are three examples of electrical overstress. Such overstress can cause failure, permanent degradation, or temporary malfunction (upset) of electronic devices and systems. This problem and general solutions are briefly reviewed. Nonlinear components and circuits for protection from electrical overstress are discussed in detail, emphasizing spark gaps, metal oxide varistors, and avalanche diodes. However, other components, such as semiconductor diodes, thyristors, resistors, inductors, and optoisolators are also discussed. Applications of these nonlinear components are discussed in the context of signal lines, AC power lines, and DC power supplies. The final chapter discusses specific upset protection circuits.

Book Description
Electronic Circuits covers all important aspects and applications of modern analog and digital circuit design. The basics, such as analog and digital circuits, on operational amplifiers, combinatorial and sequential logic and memories, are treated in Part I, while Part II deals with applications. Each chapter offers solutions that enable the reader to understand ready-made circuits or to proceed quickly from an idea to a working circuit, and always illustrated by an example. Analog applications cover such topics as analog computing circuits. The digital sections deal with AD and DA conversion, digital computing circuits, microprocessors and digital filters. This editions contains the basic electronics for mobile communications. The accompanying CD-ROM contains PSPICE software, an analog-circuit-simulation package, plus simulation examples and model libraries related to the book topics.

Book Description
This ready reference provides electrical engineers with practical information on accurate methods for measuring signals and noise in electronic circuits as well as methods for locating and reducing high frequency noise generated by circuits or external interference. Engineers often find that measuring and mitigating high frequency noise signals in electronic circuits can be problematic when utilizing common measurement methods. Demonstrating the innovative solutions he developed as a Distinguished Member of Technical Staff at AT&T/Bell Laboratories, solutions which earned him numerous U.S. and foreign patents, Douglas Smith has written the most definitive work on this subject. Smith explains design problems related to the new high frequency electronic standards, and then systematically provides laboratory proven methods for making accurate noise measurements, while demonstrating how these results should be interpreted. The technical background needed to conduct these experiments is provided as an aid to the novice, and as a reference for the professional. Smith also discusses theoretical concepts as they relate to practical applications. Many of the techniques Smith details in this book have been previously unpublished, and have been proven to solve problems in hours rather than in the days or weeks of effort it would take conventional techniques to yield results. Comprehensive and informative, this volume provides detailed coverage of such areas as: scope probe impedance, grounding, and effective bandwidth, differential measurement techniques, noise source location and identification, current probe characteristics, operation, and applications, characteristics of sources of interference to measurements and the minimization of their effects, minimizing coupling of external noise into the equipment under test by measurements, estimating the effect of a measurement on equipment operation, using digital scopes for single shot noise measurements, prediction of equipment electromagnetic interference (EMI) emission and susceptibility of performance, null experiments for validating measurement data, the relationship between high frequency noise and final product reliability. With governmental regulations and MIL standards now governing the emission of high frequency electronic noise and the susceptibility to pulsed EMI, the information presented in this guide is extremely pertinent. Electrical engineers will find High Frequency Measurements and Noise in Electronic Circuits an essential desktop reference for information and solutions, and engineering students will rely on it as a virtual source book for deciphering the "mysteries" unique to high frequency electronic circuits.
