Product Description
Simplified Design of V/F Converters shows how to design and experiment with V/F converters, both voltage-to-frequency and frequency-to-voltage. The design approach here is the same one used in all of John Lenk's best-selling books on simplified and practical design. Throughout the book, design problems start with guidelines for selecting all components on a trial-value basis, assuming a specific design goal and set of conditions. Then, using the guideline values in experimental circuits, the desired results are produced by varying the experimental component values, if needed.



If you are a working engineer responsible for designing VFCs, or selecting IC converters, the variety of circuit configurations described here should simplify your task. Not only does the book describe converter-circuit designs, but it also covers the most popular forms of VFC ICs available. Throughout the book, you will find a wealth of information on VFC ICs and related components, including how to test and troubleshoot completed circuits.

For all skill levels.

Very Disappointing
This book provides almost no information about designing VFCs despite its title. Rather it is a collection of manufacturers data sheets and application notes about how to use a limited range of prepackaged VFC/FVC chips.

Even Chapter 6 which was billed as describing "a number of discrete-component VFC and FVC circuit approaches"is only a rehash of circuits from the National Semiconductor linear handbook based round their IC implementations.

I could not recommend this book to anybody. If you have had little or no exposure to use VFC/FVCs circuits then Iwould recommend reading the Analog Devices etc. data sheets and design guides rather than wasting money on this book.

Good introductory V/F converter book
This is a good book for getting your feet wet with V/F converters.Lenk has done a good job of compiling application notes and manufacturer's tricks and techniques on V/F converter circuits into a small, easy-to-read book.

After you become acquainted with basic V/F circuits using this book, you may find yourself scouring manufacturer's websites yourself, for more in-depth information.But this book is a great start.Lenk gives the reader plenty of building-block circuits to work and learn with. ... Read more

Product Description
For very high voltage or very high current applications, the power industry still relies on thyristor-based Line Commutated Conversion (LCC), which limits the power controllability to two quadrant operation. However, the ratings of self-commutating switches such as the Insulated-Gate Bipolar Transistor (IGBT) and Integrated Gate-Commutated Thyristor (IGCT), are reaching levels that make the technology possible for very high power applications.

This unique book reviews the present state and future prospects of self-commutating static power converters for applications requiring either ultra high voltages (over 600 kV) or ultra high currents (in hundreds of kA). It is an important reference for electrical engineers working in the areas of power generation, transmission and distribution, utilities, manufacturing and consulting organizations.

All topics in this area are held in this one complete volume. Within these pages, expect to find thorough coverage on:

• modelling and control of converter dynamics;
• multi-level Voltage Source Conversion (VSC) and Current Source Conversion (CSC);
• ultra high-voltage VSC and CSC DC transmission;
• low voltage high DC current AC-DC conversion;
• industrial high current applications;
• power conversion for high energy storage.

This text has a host of helpful material that also makes it a useful source of knowledge for final year engineering students specializing in power engineering, and those involved in postgraduate research.

Product Description

Time-interleaved Analog-to-Digital Converters describes the research performed on low-power time-interleaved ADCs. A detailed theoretical analysis is made of the time-interleaved Track & Hold, since it must be capable of handling signals in the GHz range with little distortion, and minimal power consumption. Timing calibration is not attractive, therefore design techniques are presented which do not require timing calibration.

The design of power efficient sub-ADCs is addressed with a theoretical analysis of a successive approximation converter and a pipeline converter. It turns out that the first can consume about 10 times less power than the latter, and this conclusion is supported by literature.

Time-interleaved Analog-to-Digital Converters describes the design of a high performance time-interleaved ADC, with much attention for practical design aspects, aiming at both industry and research. Measurements show best-inclass performance with a sample-rate of 1.8 GS/s, 7.9 ENOBs and a power efficiency of 1 pJ/conversion-step.

Product Description

This useful monograph presents a total of seven prototypes: two double-sampled S/H circuits, a time-interleaved ADC, an IF-sampling self-calibrated pipelined ADC, a current steering DAC with a deglitcher, and two pipelined ADCs employing the SO techniques.

Product Description
The Analog to Digital Converters represent one half of the link between the world we live in -- analog -- and the digital world of computers, which can handle the computations required in digital signal processing. These devices are mathematically very complex due to their nonlinear behavior and thus fairly difficult to analyze without the use of simulation tools. High Speed A/D Converters: Understanding Data Converters Through SPICE presents the subject from the practising engineer's point of view rather than from the academic's point of view. A practical approach is emphasized.

High Speed A/D Converters: Understanding Data Converters Through SPICE is intended as a learning tool by providing building blocks that can be stacked on top of each other to build higher order systems. The book provides a guide to understanding the various topologies used in A/D converters by suggesting simple methods for the blocks used in an A/D converter. The converters discussed throughout the book constitute a class of devices called undersampled or Nyquist converters. The tools used in deriving the results presented are:+TopSpiceTM by Penzar -- a mixed mode SPICE simulator -- version 5.90. The files included in Appendix A were written for this tool. However, most circuit files need only minor adjustments to be used on other SPICE simulators such as PSpice, Hspice, IS_Spice and Micro-Cap IV;

+Mathcad 2000 -- Professional by Mathsoft. This tool is very useful in performing FFT analysis as well as drawing some of the graphs. Again, the mathcad files are included to help the user analyze the data.High Speed A/D Converters: Understanding Data Converters Through SPICE not only supplies the models for the A/D converters for SPICE program but also describes the physical reasons for the converter's performance. ...

Product Description
Power electronics is a discipline spawned by real-life applications and evolving from the need to solve power conversion problems. Historically, system implementations or circuit topologies found widespread application long before they were thoroughly analyzed. Today, however, engineers must thoroughly understand the nonlinear behavior of a system to achieve the better design, functionality, and reliability that modern applications demand.Complex Behavior of Switching Power Converters provides a systematic treatment of the procedures for observing, identifying, and diagnosing switching converter phenomena such as chaos and bifurcation. After a review of the fundamentals, the author presents some recent findings and discusses computer, laboratory, and modeling techniques for studying complex behaviors. The focus then moves to the nonlinear dynamics of various switching coverters. Here the author emphasizes circuit operation rather than mathematical abstraction, and whenever possibe, explains phenomena in terms of the physical circuit operation.Knowing when and how nonlinear phenomena occur is essential in the design and operation of power electronics. With a careful balance of theory, computer techniques, and laboratory experiments, this treatment forms a practical reference for engineers and an ideal starting point for anyone who needs a basic understanding of analyzing complex behavior in power converters. ...

Product Description
Systematic Design of Sigma-Delta Analog-to-Digital Converters describes the issues related to the sigma-delta analog-to-digital converters (ADCs) design in a systematic manner: from the top level of abstraction represented by the filters defining signal and noise transfer functions (STF, NTF), passing through the architecture level where topology-related performance is calculated and simulated, and finally down to parameters of circuit elements like resistors, capacitors, and amplifier transconductances used in individual integrators. The systematic approach allows the evaluation of different loop filters (order, aggressiveness, discrete-time or continuous-time implementation) with quantizers varying in resolution. Topologies explored range from simple single loops to multiple cascaded loops with complex structures including more feedbacks and feedforwards. For differential circuits, with switched-capacitor integrators for discrete-time (DT) loop filters and active-RC for continuous-time (CT) ones, the passive integrator components are calculated and the power consumption is estimated, based on top-level requirements like harmonic distortion and noise budget.
This unified, systematic approach to choosing the best sigma-delta ADC implementation for a given design target yields an interesting solution for a high-resolution, broadband (DSL-like) ADC operated at low oversampling ratio, which is detailed down to transistor-level schematics.
The target audience of Systematic Design of Sigma-Delta Analog-to-Digital Converters are engineers designing sigma-delta ADCs and/or switched-capacitor and continuous-time filters, both beginners and experienced. It is also intended for students/academics involved in sigma-delta and analog CAD research. ... Read more

The smart approach to convert power
I truly believe that this book is bringing good engineering approach to dc-dc converters. I personally have read a lot of diffrent books on this subject but I found this book to be both acadamic and practical. It goes through specifics without unnecessary details. Although this is not a cook book but If you are interested in the subject of power conversion, I recommend to have this book in your library. You will find it useful.

An excellent source for the detailed designer.
This book provides an essential link between the theory and application of analyzing switching power convertors. The book presents methods and techniques of analysis using modern software tools. Analysis is anessential part of designing high reliability power convertors, and thisbook provides the necessary analytical tools to accomplish the job. A musthave reference for the detailed designer.

This book gets to the heart of converter design and analysis
The authur has come up with unique methods of analyzing converters in their close loop form. He presents actual design examples showing both theoretical and measured results for several key topologies. In addition,he discusses filter design, series pass regulators, methods of convertercontrol and finally methods of modeling and simulation. I would highlyrecommend this book as a reference for the advanced designer.
