Power Electronics: Topologies, Magnetics and Control (Volume 1) The first chapter entitled: Basics of Switched-Mode Power Conversion: Topologies, Magnetics and Control was written specifically to provide a comprehensive view of Power Electronics field and to introduce novice engineers to the three key areas of expertise: Topologies, Magnetics and Control. Its first section introduces buck, boost and flyback DC-DC converters. Its second section provides an overview of properties of ferromagnetic materials culminating in modelling and design of transformers and inductors. The third section describes the general method of PWM control and regulation. This Volume 1 also introduces the fourth basic non-isolated converter type, the Cuk converter, invented on April 1, 1975. Unlike the buck, the boost and the flyback converters, this converter introduces for the first time capacitive energy transfer which led Dr. Cuk to formulate his most general State-Space Averaging Method, using the missing state-space equations for capacitor voltages and respective charge balance in addition to state-space equations for inductor currents and corresponding original volt-second balance on inductors. This method results in the general analytical model for both steady-state (DC) as well as dynamic (AC) properties for not only the existing switching converters but for all DC-DC converters based on PWM control which were known at the time and those which have been invented at any time thereafter. The Cuk converter has also motivated formulation of a new general magnetic circuits methods named Coupled-Inductors and Integrated Magnetics and demonstrated their implementation in the non-isolated and isolated Cuk converters.
Author Biography
Dr. Slobodan Cuk Dr. Cuk received his Electrical Engineering (BSEE) degree from Belgrade University, Yugoslavia in 1970 specializing in Nuclear Engineering and Control Systems. He came to the United States in 1972 and in 1973 completed a Master's Degree in Electrical Engineering at Santa Clara University sponsored by NASA. MSEE thesis: Stability Investigation of the Spinning Skylab. In 1974 he worked for MEMOREX on design of disk-drive controls. From 1974 to 1976 he completed at Caltech his PhD thesis: Modelling, Analysis and Design of Switching Converters sponsored by NASA. In August 1979 Prof. Cuk founded Optimum Power Conversion, Inc., a California corporation, (dba TESLAco) with Prof. R.D. Middlebrook. TESLAco designed hybrid DC-DC Cuk converter modules for the ORION spacecraft on a project for Honeywell and NASA. The first test flight was carried successfully in December 2014 with a manned mission to Mars scheduled for 2030. For Boeing Electronics Company TESLAco developed Cuk converters used on F-22 aircraft. From June 1977 and until December 1999, Dr. Cuk was Professor at Caltech where he taught courses in Power Electronics and advised 35 PhD students Dozen of his students are now Professors of Power Electronics in US and worldwide. For the invention of Integrated Magnetics and the Cuk converter, Prof. Cuk and Prof. Middlebrook received 1991 Medal from Franklin Institute in Philadelphia. Dr. Cuk's publications include over 150 scientific papers. The original two volumes paperback edition published by TESLAco in 1981 was used as a first introduction to Power Electronics by many engineers and by over 4,000 engineers who attended Dr. Cuk's public courses worldwide. New Hybrid, Storageless and PWM/Resonant Switching Methods pioneered by Dr. Cuk have already resulted in two dozen novel converter topologies covered by US and worldwide patents. Dr. Cuk's key inventions are: Optimum Topology Converter, known as the Cuk converter (1974) Coupled-Inductor and Integrated Magnetics Methods (1975) State-space Averaging Method (1975). Tesla Converter (2000) Hybrid and Storageless Switching Methods (2009) Bridgeless AC-DC converters with PFC and Isolation (2010) Isolated Cuk-Boost Converter (2012) Cuk-buck 2 Converter (2013) Single-Phase and Three- Phase Cuk-rectifier (2014) Rapid, On-Board Cuk-Charger for Electric Vehicles (2015) PWM-Resonant Switching Method (2015)
