Control Design Techniques in Power Electronics Devices deals specifically with control theories relevant to the design of switched power electronics, for the most part, DCDC converters and supplies, rectifiers of different kinds and inverters with varying topologies. The theoretical methods for designing controllers in linear and nonlinear systems are accompanied by case studies and examples showing their application. The book is introduced through the important topic of modeling switched power electronics as controlled dynamical systems. There are circuit layouts, schematics and actual closed-loop control responses, generated by applying the theory, from a representative group of the plants under discussion. Among the control theories which feature in the book are: sliding mode control, feedback control by means of approximate linearization and nonlinear control design methods. This monograph will be of interest to researchers, tutors and students in power systems and their related control problems.
