OVERVIEW With this revised edition we aim to present a text on Power Electronics for the UG level which will provide a comprehensive coverage of converters, choppers, inverters and motor drives. All this, with a rich pedagogy to support the conceptual understanding and integral use of PSPICE. Key Features: Focus on Process Design than Mechanical Design: leading to understanding of design of a chemical plant. Plenty of Process Flow Diagrams (PFD) and Piping and Instrumentation Diagrams (P&ID), detailing of the steps followed in their preparation and interpretation. (chapter 4) State-of-the-art technique of supercritical extraction discussed with design of extractors. Chapter 5 on Flow of Fluids discusses various new aspects like design and calibration of rotameters, 2 phase flow etc. with industrial applications. Extensive discussions on design of Heat Exchangers with specific applications in chemical plants are given in chapter 6.
