Christophe P. Basso is currently an engineering director at ON Semiconductor in France, where he has developed numerous popular switching power supply controllers, for instance, for the notebook adapter business. He is the author of several books on power electronics, including McGraw-Hills Switch-Mode Power Supply SPICE Cookbook, and, recently, he released a title 100% dedicated to loop control, Designing Control Loops for Linear and Switching Power Supplies. He regularly teaches professional seminars at IEEE-sponsored Applied Power Electronics Conferences and often publishes articles in trade magazines such as PET and the online newsletter How2Power. Mr. Basso graduated from the Montpellier University in 1985, and he received his M.S.E.E. in power electronics from the National Polytechnic Institute of Toulouse in 2008. He holds 29 patents in the field of power electronics and he is an IEEE Senior Member.

I am glad to introduce the second edition of my 2008 book Switch-Mode Power Supplies: SPICE Simulations and Practical Designs. I would like to thank all the readers who have contributed to make the first edition a success. I received numerous warm and supportive messages from all around the world and it is extremely rewarding. Without you, this new book would not exist. Some of these readers have been kind enough to report typos and errors they found in the first edition. I compiled them throughout the years and I used the list to clean equations and figures.

Revising a book is not an easy task, as some readers will object that there is too little renewed content to make it a new book while others complain that this new edition represents a completely different document than the first one they bought! Needless to say, trying to please both parties is a perilous exercise. Loyal to my original approach, I added topics in which I detailed the mathematical treatment so that you can follow and learn from the book. In includes a new small-signal model of the active clamp forward converter operated in voltage-mode control.

I hope you will enjoy reading this second edition, in particular the newly added materials. Despite all my efforts, some typos or mistakes may have escaped my attention and I would be grateful if you would send your corrections/remarks to for the benefit of the reading community. I thank you in advance and wish you the best of luck for your designs!

My warmest thanks and love go first of all to my dear family: Anne, my wife, and my two beloved children, Lucile and Paul. Revising an entire 900-page book cannot be done overnight and I am grateful I could spend endless hours correcting and writing new paragraphs without affecting family life. Now that it is done, I will enjoy hiking, cycling, reading, snowshoeing, and spending leisure time with you all again!

The book revision could not have been envisaged without the help and involvement of many people. I wish to thank Jol Turchi, my friend and colleague at work, who is always available to discuss technical subjects for hours and review my work. These discussions also took place with the application team with whom I am lucky to work: Thierry Sutto, Stphanie Cannenterre, Yann Vaquette, and Dr. Jos Capilla. They kindly reviewed this second editions materials. Special thanks go to Alain Laprade of ON Semiconductor in East Greenwich who kindly reviewed several chapters.
