George C. Verghese Books

For upper-level undergraduate courses in deterministic and stochastic signals and system engineering, this comprehensive text builds on foundational courses in time- and frequency-domain analysis of signals and systems, as well as probability. Aimed at upper-level undergraduates and beginning graduate students in engineering and applied sciences, it pioneers a novel course of study that bridges introductory and advanced subjects. The text reviews properties and representations of deterministic signals and systems, covering group delay and state-space model behavior. It also introduces correlation functions and power spectral densities for processing random signals. Application contexts include pulse amplitude modulation, observer-based feedback control, optimum linear filters for minimum mean-square-error estimation, and matched filtering for signal detection. Emphasizing model-based approaches to inference, it addresses state estimation, signal estimation, and detection. The book explores concepts and tools relevant across various fields, including signal processing, control, communication, time-series analysis, financial engineering, and biomedicine. This flexible and long-awaited text is suitable for a rigorous course in a wide range of engineering and applied science curricula.

Substantially expanded and updated, the new edition of this classic textbook provides unrivalled coverage of the fundamentals of power electronics. Comprehensive coverage of foundational concepts in circuits, magnetics, devices, dynamic models, and control establishes a strong conceptual framework for further study. Extensive discussion of contemporary practical considerations, enhanced by real-world examples, prepares readers for design scenarios ranging from low-power dc/dc converters to multi-megawatt ac machine drives. New topics include SiC and GaN wide-bandgap materials, superjunction MOSFET and IGBT devices, advanced magnetics design, multi-level and switched-capacitor converters, RF converter circuits, and EMI. Over 300 new and revised end-of-chapter problems enhance and expand understanding of the material, with solutions for instructors. Unique in its breadth and depth, and providing a range of flexible teaching pathways at multiple levels, this is the definitive guide to power electronics for graduate and senior undergraduate students in electrical engineering, and practicing electrical engineers.
