Electrotechnical Systems

Thanks to advances in mathematical methods and computer technology, labor productivity during the analysis and development of electrotechnical devices has increased. This book explores the possibilities of the Mathematica and PSpice program for analyzing processes in power electronic systems. The authors discuss the formulation of problems and the steps in their solution. They focus on the analysis of transient, steady-state processes and their stability in nonstationary and nonlinear systems with DC and AC converters. All problems are solved by Mathematica and program codes are presented. The PSpice program is used for comparison of results obtained with Mathematica and shows the peculiarities of its utilization.
