This book was released on 2018-10-06 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the applications of Equivalent-Small-Parameter Method (ESPM) in solving the steady-state periodic solutions, as well as stability analysis, of kinds of open-loop or closed-loop operated DC/DC converters, such as PWM, quasi-resonant and resonant ones. The analytical expressions of DC components and harmonics of state variables (inductor current and capacitor voltage) with DC/DC converters can be obtained by ESPM, which can be helpful to understand the nonlinear operating mechanism of switched-mode converters. It can also be useful for stability analysis and design for practical converters. Modeling and analysis on all kinds of DC/DC converters are introduced in detail in this book, along with a large amount of simulation or experimental waveforms to verify the correctness of the theoretical analysis based on ESPM.

This book was released on 2020-07-03 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a detailed analysis of switched-capacitor DC-DC converters that are entirely integrated on a single chip and establishes that these converters are mainly limited by the large parasitic coupling, the low capacitor energy density, and the fact that switched-capacitor converter topologies only have a fixed voltage conversion ratio. The authors introduce the concept of Advanced Multiphasing as a way to circumvent these limitations by having multiple out-of-phase parallel converter cores interact with each other to minimize capacitor charging losses, leading to several techniques that demonstrate record efficiency and power-density, and even a fundamentally new type of switched-capacitor topology that has a continuously-scalable conversion ratio. Provides single-source reference to the recently-developed Advanced Multiphasing concept; Enables greatly improved performance and capabilities in fully integrated switched-capacitor converters; Enables readers to design DC-DC converters, where multiple converter cores are put in parallel and actively interact with each other over several phases to improve their capabilities.

This book was released on 2022-06-01 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computers play an important role in the analyzing and designing of modern DC-DC power converters. This book shows how the widely used analysis techniques of averaging and linearization can be applied to DC-DC converters with the aid of computers. Obtained dynamical equations may then be used for control design. The book is composed of two chapters. Chapter 1 focuses on the extraction of control-to-output transfer function. A second-order converter (a buck converter) and a fourth-order converter (a Zeta converter) are studied as illustrative examples in this chapter. Both ready-to-use software packages, such as PLECS® and MATLAB® programming, are used throught this chapter. The input/output characteristics of DC-DC converters are the object of considerations in Chapter 2. Calculation of input/output impedance is done with the aid of MATLAB® programming in this chapter. The buck, buck-boost, and boost converter are the most popular types of DC-DC converters and used as illustrative examples in this chapter. This book can be a good reference for researchers involved in DC-DC converters dynamics and control.

Download or read book Analytical Modeling and Design of High Efficiency Fully-integrated Switched-capacitor DC-DC Converters and a High-voltage Current Regulator written by Anurag Veerabathini and published by . This book was released on 2018 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: A high-voltage micro-ampere current regulator is introduced that ensures a constant ion current in order to stabilize measurements in analytical ion instruments. The current regulator is placed in series with a high-voltage power supply and a corona discharge ionization source. The proposed current regulator stabilizes the current in the corona without requiring a portion of the corona ion current sampled. The current regulator includes a first feedback circuit to provide rapidly-adapting current regulation, and an optional secondary feedback which provide slowly-adapting current regulation. The secondary feedback circuit senses the voltage across the high-voltage current regulator and slowly varies a high-voltage power supply to improve the long-term stability. Measured results demonstrate 10 kV of isolation and an adjustable current range from 1 to 50 [mu]A.

Download or read book Modeling the Practical Performance of Switched-capacitor Converters and a Method for Automating State-space Model Generation written by Jordan Michael Henry and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A new modeling technique and a method for automating the modeling process are introduced for analyzing complex switched-capacitor (SC) converters. The model uses conventional circuit analysis methods to derive state-space models of each switching state. Steady-state performance is derived and expressed as an equivalent resistance. Whereas previous techniques have provided either the detailed performance of a simple SC converter or the limiting performance of a complex SC converter, this new model is flexible enough to provide detailed performance for any practical converter. Nonuniform component choices, asymmetric duty cycles, and other deviations from an ideal converter can be readily included. Dynamics can also be analyzed. Iterative methods of design based on this model would require the formulation of many equations, which is time consuming if done manually. Therefore, an algorithm is introduced to automatically generate the equations required for this state-space based modeling. The state equations are generated algorithmically given a standard node incidence matrix generated from a user-defined netlist. The algorithm enables a designer to quickly iterate SC converter design solutions based on its predicted performance. The model and algorithm have been validated through simulation techniques and experimental data collected from laboratory testing"--Abstract, leaf iii

This book was released on 2016 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates a new reconfigurable switched-capacitor (SC) based partial power architecture which enhances the performance of resonant DC/DC converters operating at radio frequency (RF) with gallium nitride (GaN) power devices to address challenges in telecommunication brick DC/DC converters. The proposed architecture has a comprehensive compatibility with existing RF and SC topologies and improves the performance of RF converters through partitioning of energy conversion stage and output regulation stage. Emerging new wide bandgap devices like GaN FETs enable a higher power density DC/DC converter design. A wider input range, larger voltage conversion ratio, smaller size, and excellent transient performance are expected. The prototype of the proposed GaN reconfigurable SC-based partial power RF converter comprises of a 20 MHz resonant single-ended-primary-inductor-converter (SEPIC) as a regulated stage and a high-efficiency 2 MHz reconfigurable SC as an unregulated stage. The GaN RF resonant SEPIC regulates the output using a robust ON/OFF control scheme, which enables fast transient responses. The high-efficiency GaN reconfigurable SC provides 1:1, 2:1 and 3:1 voltage conversion ratio which widens the input voltage range. A full time-domain, closed-form analytical model for RF resonant SEPIC has been developed, and new design methodology has been proposed for the GaN reconfigurable SC to address the design challenges at megahertz. The electromagnetic interference (EMI) characteristics of the prototype have also been investigated and evaluated by experiments. An alternative control scheme and PCB layout guidelines have been developed for EMI reduction.

Download or read book Switch-Mode Power Converters written by Keng C. Wu and published by Elsevier. This book was released on 2005-12-01 with total page 409 pages. Available in PDF, EPUB and Kindle. 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
