Power Electronic Systems : Walsh Analysis with MATLAB®

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 electronic systems and their optimization.

A Totally Different Outlook on Power Electronic System Analysis

Power Electronic Systems: Walsh Analysis with MATLAB® builds a case for Walsh analysis as a powerful tool in the study of power electronic systems. It considers the application of Walsh functions in analyzing power electronic systems, and the advantages offered by Walsh domain analysis of power electronic systems.

This book successfully integrates power electronics as well as systems and control. Incorporating a complete orthonormal function set very much unlike the sine–cosine functions, it introduces a blending between piecewise constant orthogonal functions and power electronic systems. It explores the background and evolution of power electronics, and discusses Walsh and related orthogonal basis functions. It develops the mathematical foundation of Walsh analysis, and first- and second-order system analyses by Walsh technique. It also describes the Walsh domain operational method and how it is applied to linear system analysis.

While presenting the underlying principles of Walsh analysis, the authors incorporate many illustrative examples, and include a basic introduction to linear algebra and MATLAB® programs. They also examine different orthogonal piecewise constant basis functions like Haar, Walsh, slant, block pulse functions, and other related orthogonal functions along with their time scale evolution.
