This third edition illustrates the integration of the industry standard software as a tool for design verification and as a theoretical laboratory bench. The book presents examples of all types of power converters as well as circuits with linear and nonlinear inductors. A new chapter covers multi-level converters. Assuming no prior knowledge of SPICE or PSPICE simulation, the text provides detailed step-by-step instructions on how to draw a schematic of a circuit, execute simulations, and view or plot the output results. It also includes suggestions for laboratory experiments and design problems that can be used for student homework assignments.
