This book is about the techniques of advances and recent trends in power Electronics to the professional community with the expectation that it will be given the same wide and enthusiastic acceptance by practising engineers, R & D Professionals, University professors and even graduate students that my other books in this area have unlike the traditional books available in the area of power electronics, this book has a unique presentation format that makes it convenient for group presentations. Next to having an actual system to experiment on, power electronics is often chosen by engineers to study transient and control performance or to test conceptual designs. Its use in teaching is growing now that inexpensive and powerful personal computers with simulation capabilities previously available only in specialized facilities are widely accessible to students. There are many excellent textbooks on electric machine models, operating principles and steady state Characteristics, but few dwell on the implementation of simulations.
