Converters in Equilibrium There are no substantial changes to the chapters of Part 1. Chapter 2 Principles of Steady-State Converter Analysis l Chapter 3 Steady-State Equivalent Circuit Modeling, Losses, and Efficiency l Chapter 4 Switch Realization l Chapter 5 The Discontinuous Conduction Mode l Chapter 6 Converter Circuits l Part 2. Converter Dynamics and Control Chapter 7 AC Equivalent Circuit Modeling l Chapter 7 has been revised to improve the logical flow, including incorporation of the First Edition Appendix 3 into the chapter. The treatment of circuit averaging and averaged switch modeling (Section 7.4) has undergone major revision. Other changes include Fig. 7.4 and the related text, and Sections 7.2.2, 7.2.7. Chapter 8 Converter Transfer Functions l Major revisions to Chapter 8 include a new introduction, a new input filter example in Section 8.1.8, and substantial changes to the buck-boost converter example of Section 8.2.1 and the material of Sections 8.3 and 8.4. Chapter 9 Controller Design l Only minor changes to Chapter 9 were made. Chapter 10 Input Filter Design l This is an entirely new chapter that treats how input filters modify the transfer functions of a dc-dc http://ece-www.colorado.edu/~pwrelect/book/SecEd.html (3 of 6) [25/04/2002 16:42:05] Revision to Fundamentals of Power Electronics converter, and how to design an input filter that is adequately damped. The approach is based on Middlebrook's Extra Element Theorem (EET) of Appendix C, although it is possible to teach this chapter without use of the EET. Chapter 11 AC and DC Equivalent Circuit Modeling of the Discontinuous Conduction Mode l This chapter has been entirely revised and simplified. Chapter 12 Current Programmed Control l Treatment of the "more accurate model" in Section 12.3 has undergone a major revision. The explanation is more straightforward, and results are summarized for the basic buck, boost, and buck-boost converters. The results of simulation are used to illustrate how current programming changes the converter transfer function. The treatment of discontinuous conduction mode in Section 12.4 has been shortened. Part 3. Magnetics Chapter 13 Basic Magnetics Theory l The material on the skin and proximity effects has undergone a major revision, to better introduce the concepts of the proximity effect and MMF diagrams. The summary of operation of different magnetic devices has been moved from the filter inductor design chapter into this chapter. Chapter 14 Inductor Design l A new section on design of multiple-winding inductors using the Kg method has been added, including two new examples. The summary of different magnetic devices has been moved to the previous chapter, and the material on winding area optimization (previously in the transformer design chapter) has been moved into this chapter. Chapter 15 Transformer Design l Notation regarding maximum, peak, and saturation flux density has been made more clear. The section on winding area optimization has been moved to the previous chapter. Part 4. Modern Rectifiers, Inverters, and Power System Harmonics http://ece-www.colorado.edu/~pwrelect/book/SecEd.html (4 of 6) [25/04/2002 16:42:05] Revision to Fundamentals of Power Electronics Chapter 16 Power and Harmonics in Nonsinusoidal Systems l Information on harmonic standards has been updated. Chapter 17 Line-Commutated Rectifiers l There is little change to this chapter. Chapter 18 Pulse-Width Modulated Rectifiers l Chapter 18 is a consolidation of Chapters 17 and 18 of the First Edition. The material has been completely reorganized, to improve its flow. A new section 18.2.2 has been added. Section 18.3.3 has been expanded, to better cover critical conduction mode control. The material on three-phase rectifier topologies has been streamlined. Part 5. Resonant Converters Chapter 19 Resonant Conversion l The order of the sections has been changed, to improve readability. Section 19.4 has been modified, to include better explanation of resonant inverter/electronic ballast design, and two examples have been added. The material on the ZVT converter has been moved to Chapter 20. Chapter 20 Soft Switching l A new Section 20.1 compares the turn-on and turn-off transitions of diode, MOSFET, and IGBT devices under the conditions of hard switching, zero-current switching, and zero-voltage switching. The material on quasi-resonant converters is unchanged. Coverage of multi-resonant and quasi-squarewave switches has been exapanded, and includes plots of switch characteristics. A new Section 20.4 has been added, which covers soft-switching techniques. Included in Section 20.4 is an expanded explanation of the ZVT full-bridge converter, new material on active-clamp snubbers, and a short treatment of the auxiliary resonant commutated pole. The material on ac modeling of ZCS quasi-resonant converters has been dropped.
