Available in PDF, EPUB and Kindle. Book excerpt: "Power Converter with capacitive input filter is a non-linear load to the Utility AC power lines. There are widely used as Switch-Mode Power Supplies in office equipment applications ranging from Personal Computers to Office Printers and Copiers. The distorted input current waveform extracted by the capacitive input filter of the power converters produces unwanted harmonics which propagates to other line powered equipments. The harmonic pollutes the AC lines and interferes with the operations of sensitive line powered equipments. The distorted current waveform also leads to inefficient utilization of the available power from the AC outlet. This is because the AC line power is transferred to the load only when each frequency component of the line voltage is an in-phase, scaler related quantity with respect to the same frequency component of the extracted current. The problems of poor power factor and harmonic distortion are compounded by the proliferation of Switch-Mode power supplies and the situation is rapidly becoming intolerable. The problem of poor quality input current waveform can be described by two quantitative measurements: Power Factor (pf) and Total Harmonic Distortion (thd). Two general approaches are available to remedy the problem. One approach is to install passive filter networks between the Utility AC lines and the capacitive input filter. The second approach is to design active power processors as dedicated Power Factor Correction (pfc) Converters and installed as the front end to the capacitive input filter to shape the distorted current waveform into waveforms which will yield higher power factor. This Thesis first introduce the general concept of PF and harmonic distortion in Chapter 1. Chapter 2 derive the mathematical description of pf based on the concept of real power (pR) and apparent power (pA). Both sinusoidal and nonsinusoidal cases are studied. For comparison and completeness, two popular passive power factor correction filter networks are analyzed in Chapter 3 to derive the maximum achievable power factor for each network along with the corresponding harmonic distortions. Governing equations are derived and presented graphically as a function of the filter network and load parameters. Chapter 4 provides the analysis of active power factor correction using switch mode Boost Converter. The analysis is carried out for two types of current controllers used as the current modulators for current waveform shaping. The state space averaged modeling approach is employed to derive the mathematical model of the Boost Converter suitable for large signal time domain and small signal frequency domain analysis. The model is further extended to derive the describing equations for the Boost Converter operating as pfc converter. Characteristics of the two current controller functions impacting the pfc operation are studied to expose their relative strength and limitations. The analysis includes the supplementation of the current control loop by an outer voltage control loop to regulate the output capacitor voltage of the pfc converter. The large signal analysis is first investigated for PF, waveform quality and voltage regulation. The small signal analysis follows to extract the frequency domain behavior of the pfc Boost Converter. The limitation of the voltage control bandwidth and its effect on the achievable pf is discussed. Chapter 5 verified the analysis through computer simulation using PSPICE. The original works of Bello based on Berkeley SPICE are modified for PSPICE. The models are extended to implement the PFC control functions and simulated in both large signal time domain and small signal frequency domain. Both the analysis and computer simulation results are compared to a published design of pfc Converter."--Abstract.

Book excerpt: Switch-Mode Power Converters introduces an innovative, highly analytical approach to symbolic, closed-form solutions for switched-mode power converter circuits. This is a highly relevant topic to power electronics students and professionals who are involved in the design and analysis of electrical power converters. The author uses extensive equations to explain how solid-state switches convert electrical voltages from one level to another, so that electronic devices (e.g., audio speakers, CD players, DVD players, etc.) can use different voltages more effectively to perform their various functions. Most existing comparable books published as recently as 2002 do not discuss closed-loop operations, nor do they provide either DC closed-loop regulation equations or AC loop gain (stability) formulae. The author Wu, a leading engineer at Lockheed Martin, fills this gap and provides among the first descriptions of how error amplifiers are designed in conjunction with closed-loop bandwidth selection. BENEFIT TO THE READER: Readers will gain a mathematically rigorous introduction to numerous, closed-form solutions that are readily applicable to the design and development of various switch-mode power converters. Provides symbolic, closed-form solutions for DC and AC studies Provides techniques for expressing close-loop operation Gives readers the ability to perform closed-loop regulation and sensitivity studies Gives readers the ability to design error amplifiers with precision Employs the concept of the continuity of states in matrix form Gives accelerated time-domain, steady-state studies using Laplace transform Gives accelerated time-domain studies using state transition Extensive use of matrix, linear algebra, implicit functions, and Jacobian determinants Enables the determination of power stage gain that otherwise could not be obtained

This textbook is ideal for senior undergraduate or graduate courses in power electronic converters, requiring only systems analysis and basic electronics courses. The only text of such detail to also include the use of PSpice and step-by-step designs and simulations, Power-Switching Converters, Second Edition covers basic topologies, basic control techniques, and closed-loop control and stability. It also includes two new chapters on interleaved converters and switched capacitor converters, and the authors have added discrete-time modeling to the dynamic analysis of switching converters. The final two chapters are dedicated to simulation and complete design examples, respectively. PSpice examples and MATLAB scripts are available for download from the CRC Web site. These are useful for the simulation of students' designs. Class slides are also available on the Internet. Instructors will appreciate the breadth and depth of the material, more than enough to adapt into a customized syllabus. Students will similarly benefit from the more than 440 figures and over 1000 equations, ample homework problems, and case studies presented in this book.
