Focusing on Walsh/block pulse domain analysis, this book presents orthogonal Walsh functions for analyzing power electronic systems. It covers two major members of the piecewise constant orthogonal function family: orthogonal Walsh and block pulse functions. These bi-valued functions are compatible to digital processing and by increasing the number of component functions, a continuous-like solution can be obtained. The book shows how the methods are useful for power energetic systems and their optimization.

Anish Deb obtained his BTech in 1974 (recipient of Calcutta University silver medal), MTech in 1976 (recipient of Calcutta University gold medal and P. N. Ghosh memorial gold medal), and PhD (Tech) in 1990 from the Department of Applied Physics, University of Calcutta, India. In 1978, he joined the Department of Applied Physics, University of Calcutta, as Lecturer in 1983. In 1990, he became Reader (associate professor) in the same department. He has been holding the post of Professor since 1998. His research interest includes automatic control in general and application of "alternative" orthogonal functions in power electronics and systems and control. He has authored one book entitled "Triangular orthogonal functions for the analysis of continuous time systems" and published more than 65 research papers in different national and international journals and conferences.Suchismita Ghosh obtained her BTech (2008) from the Calcutta Institute of Engineering and Management, West Bengal University of Technology, India, and MTech (2010) from the Department of Applied Physics, University of Calcutta, India. She is currently an assistant professor in the Department of Electrical Engineering, MCKV Institute of Engineering, West Bengal University of Technology, India. She has taught courses on power electronics, basic electrical engineering, control systems, and electrical machines. Her research area includes automatic control in general and application of "alternative" orthogonal functions in systems and control. She is presently involved in research with Anish Deb and has published five research papers in international journals and national conferences.
