This book is designed for Undergraduate and Postgraduate students of electrical and electronics engineering and also for the Professionals. The objective of the book is to explain the operations of all important power semiconductor devices such as IGBTs, ETOs, IGCTs, etc., that are used to control power systems and show how the devices are used in appropriate circuit and devices. The author has tried to cover as many applications as possible and give sufficient information which can influence the students and practitioners to move towards the design of programmable power systems.
KEY FEATURES
Extensive use of MATLABĀ® based examples to provide a better understanding of the subject. The book employs a pedagogical structure designed to take full advantage of MATLAB and to avoid the pitfalls of a cook-book approach to problem. solving. Each chapter begins with the essential theory along with related waveforms and then describes the MATLAB programs with their corresponding outputs. MATLAB codes in the form of m-file are provided with sufficient details to allow the students to repeat the examples on their computers. More than 35 programs in the text that have been tested and included in a CD under MATLAB 6.5 version or higher.
