| Beschreibung: | Power Supply design is all about detail. And a large part of that detail lies in the practical domain, largely because of the typically small number of microseconds of switching periods involved, and the even smaller tens of nanoseconds of switch transition times --- all these, in effect accentuating various "second-order" effects, that eventually end up playing prime havoc with "normal" expectations of how the circuit should behave. So not unsurprisingly, even after reading several books, most readers still find themselves no closer to the ultimate goal of designing an actual power supply. Sooner or later, all engineers start realizing the hard fact that designing a switching power supply isn't the trivial task it once seemed to be. But even after years of successfully mastering the underlying theory, the ultimate goal of creating a cost-effective, reliable and commercially viable power supply may still remain a distant dream, since success ultimately hinges on experience. That is, in fact, what clearly differentiates a senior and seasoned power supply engineer from the others --- the ability to navigate and surmount a veritable minefield of tricky issues that can only be learned the hard way, by actual hands-on experience on the job. This book presents practical knowledge the author acquired rather painfully, while working "in the trenches" for several years in major engineering companies scattered across several continents. This is intended to be the mythical senior engineer's "bag of tricks," finally made available in the form of an easy-to-read book on your shelf. This book will make life for the ambitious power supply engineer much simpler --- besides reducing significantly, the rigorous requirement of having to be a senior engineer's proťǧ for years on end, just to gain a small measure of real success in this field. * A practical presentation that answers the important question: why is my switching converter behaving so differently than what I was expecting on the basis of my paper design? And how do I bridge that huge gap? * For the first time, a systematic and thorough discussion of troubleshooting switching power supplies. * Coverage of AC/DC and DC/DC power supplies. * Bench Evaluation of semiconductor ICs used in power conversion --- describing standard and unusual techniques mastered by the author, while testing similar chips at National Semiconductor. * Detailed coverage of vital topics that haven't been covered by available sources --- grounding systems, the subtleties of component datasheets, and using instruments and probes effectively. * Systematic investigation (type of failure mechanism, topology, etc.) and solutions for 5 years of reported power supply issues on a prominent, public web forum.

This book will make life for the ambitious power supply engineer much simpler --- besides reducing significantly, the rigorous requirement of having to be a senior engineer's proťǧ for years on end, just to gain a small measure of real success in this field. * A practical presentation that answers the important question: why is my switching converter behaving so differently than what I was expecting on the basis of my paper design? And how do I bridge that huge gap? * For the first time, a systematic and thorough discussion of troubleshooting switching power supplies. * Coverage of AC/DC and DC/DC power supplies. * Bench Evaluation of semiconductor ICs used in power conversion --- describing standard and unusual techniques mastered by the author, while testing similar chips at National Semiconductor. * Detailed coverage of vital topics that haven't been covered by available sources --- grounding systems, the subtleties of component datasheets, and using instruments and probes effectively. * Systematic investigation (type of failure mechanism, topology, etc.) and solutions for 5 years of reported power supply issues on a prominent, public web forum. This approach will ensure that engineers will not repeat the same mistakes. * A unique, readable style: personal and direct; no mystification--- just the plain truth, easily and logically explained, with plenty of pictures, graphs and plots The practical relationship between efficiency and duty cycle; Understanding datasheets and selecting the right components; Power IC bench evaluation and Selection; Proper PCB layout Practices; Practical buck converters; The Forward Converter; Practical boost converters; The PFC boost pre-regulator; Practical buck-boost converters; The off-line Flyback converter; Bench setup and grounding issues; Lab Instrumentation; General Measurements and Troubleshooting Techniques; Specific Troubleshooting Scenarios: High Output ripple and noise, Poor Load transient response, Poor Output voltage regulation, Start-up problems, Unwanted and Desirable Jitter, Alternate Cycle Instabilities, Loop compensation issues, Catastrophic Blow-ups, Output foldback or shutdown, Improperly set Current limit issues, Short circuit, Over-voltage, Short-term and Long-term Thermal failures, Mysterious System Shutdowns, Magnetic saturation failures, Safety issues, Troubleshooting EMI, Line surge test failures, ESD related failures, Acoustic noise issues and techniques to circumvent, Mechanical failures, Diagnosing Low efficiency, Poor reliability and Stress testing, Vibration Testing, Burn-in/HAST/HALT/Overstress/DRT Tests, Design for Manufacturability issues; Sample Component Datasheets; Choosing the Right Inductor for your Application; 5 years of reported problems; Reference Tables and Graphs for Quick Design and Validation Includes bibliographical references and index TECHNOLOGY & ENGINEERING / Electrical bisacsh Electric current converters fast Semiconductor switches fast Switching power supplies fast Electric current converters Semiconductor switches Switching power supplies Fehlersuche (DE-588)4016615-6 gnd rswk-swf Schaltnetzteil (DE-588)4124127-7 gnd rswk-swf Schaltnetzteil (DE-588)4124127-7 s Fehlersuche (DE-588)4016615-6 s 1\p DE-604 http://search.ebscohost.com/login.aspx?direct=true&scope=site&db=nlebk&db=nlabk&AN=205729 Aggregator Volltext 1\p cgwrk 20201028 DE-101 https://d-nb.info/provenance/plan#cgwrk |
