This book is the most comprehensive study available of the theoretical and practical aspects of controlling and measuring Electromagnetic Interference in switching power supplies, including input filter instability considerations.

The new edition is thoroughly revised with six completely new chapters, while the existing EMI chapters are expanded to include many more step-by-step numerical examples and key derivations and EMI mitigation techniques. New topics cover the length and breadth of modern switching power conversion techniques, lucidly explained in simple but thorough terms, now with uniquely detailed "wall-reference charts" providing easy access to even complex topics.
Step-by-step and iterative approach for calculating high-frequency losses in forward converter transformers, including Proximity losses based on Dowell's equationsThorough, yet uniquely simple design flow-chart for building DC-DC converters and their magnetic components under typical wide-input supply conditionsStep-by-step, solved examples for stabilizing control loops of all three major topologies, using either transconductance or conventional operational amplifiers, and either current-mode or voltage-mode control"

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 protege 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."

Sanjaya Maniktala, author of several well-known technical books, has written this genre-defying, tongue-in-cheek novel. Ken Coffman, accomplished author of eight books says: "It's a kaleidoscopic collage of snapshot memories, and like all good books, leaves us breathlessly wanting more. The playful language and multicultural commentary is simply delightful."

This "quirky memoir," as Coffman aptly calls it, is sadly bereft of any heart-rending stories about rummaging through empty dumpsters. There is nothing singularly uplifting on any single page. But it was never intended to get you to cry your heart out. It was only meant to make you smile from ear to ear. To be incredibly interesting.

There are fascinating multicultural quirks in abundance here, spanning decades spent criss-crossing through several cities in India, Germany, Singapore and the US. Plus life at two of India's most prestigious colleges, IIT Bombay and St. Stephen's College, Delhi. Feel the intensity and diversity of a completely different world out there.

Intertwined with the author's personal story is also the unforgettable tale of a well-known secessionist movement of India. At least two high-profile assassinations took place as a result, including that of the former Prime Minister of India, Mrs. Indira Gandhi. The parallel historical track of this memoir includes some details of that era, which perhaps, only the author was in a position to hear about and relate for the very first time here. You are warned: there are some grim moments as a result.

Here is a sample:

An official witness to the legal ceremony was a perpetually plastered lawyer named Mr. Bhinde. I had met him a few days ago when I had gone to the court to enquire about the general procedure, and it was now obvious to me, that he had not been dry for a minute ever since. But I also realized that good things come in pairs. Pretty soon, Mr. Bhinde had brought in another equally inebriated friend of his from somewhere out there - to complete the remaining drunken witness signature line on the imposing paperwork. Much to our good fortune, the magistrate seemed sober enough, and declared us man and wife shortly thereafter. I could have sworn he didn't stutter even once.

As we were trying to make our way out, I spotted Mr. Bhinde still lurching around helpfully in the crowds milling around the main courtroom. I came up from behind him, and after a little trial and error, managed to place a hand on his wavering shoulder. I handed him a box of Indian candy (gulab jamun) to mark the auspicious occasion. For a minute he turned around looking somewhat puzzled, as if we should have known all along that he would have preferred a bottle of Old Monk rum instead. But then he smiled. It was clear Mr. Bhinde's heart, if not his liver, was still in the pink of health. Touched by our sweet gesture, he started looking beseechingly at us as if we were the last people in the big wide world who still cared about him. And perhaps we were Then he burst into tears. Soon he was sitting there sobbing uncontrollably on the stairs of the majestic building, large tear drops streaming down his scrawny face, as a small crowd gathered around to watch with growing amusement. He proceeded to relate the story of his entire wretched life, starting from that dull rainy day when he was born to destitute parents under a nameless bridge somewhere deep within the squalor of Calcutta. He cried his heart out that ever since, he had consistently "failed to live up to his mama's expectations" (Looks like I wasn't the only one haunted by such dark remorseful thoughts). He expressed eternal sadness that he had turned out to be such an "utter failure of a son." He cried out: "Think what hopes dearest Mum must have had from her one and only child, but look at what he has turned out to be. He couldn't even gift her a nice devout daughter-in-law, to take care of her in her old age."
