Book Synopsis Analysis and Control of the Chaotic Behavior in a Multi-Cell DC/DC Buck Converter by : Karama Koubaâ
Download or read book Analysis and Control of the Chaotic Behavior in a Multi-Cell DC/DC Buck Converter written by Karama Koubaâ. This book was released on 2018. Available in PDF, EPUB and Kindle. Book excerpt: "Multi-cell power converters have been widely used in real applications since they circumvent shortcomings of ordinary switching devices due to their ability to support high-voltages. In this book, we deal with the case of an N-cell DC/DC buck converter, and we present a systematic method to control the voltage across the flying capacitors and the current through the load that can be generalized from a two-cell converter to an N-cell converter. The system was described by a discrete-time model through some simplifying assumptions to derive easily the general model in the form of a recurrence equation, which is useful in the design of control laws and exhibits chaotic behavior, bifurcations and strange phenomena when applying feedback control methods. In addition, the problem of the windup phenomenon, which is caused by the effect of switching, was discussed along with an anti-windup approach that was developed and successfully applied to the controlled DC/DC buck converter. A generalization of the various control laws adopted and a comparison between the results obtained with these methods were given, including the performance of the controlled system and the types of bifurcations encountered. Throughout this work, it has been shown that as the number of cells in the converter increases, the complexity of the uncontrolled system model and the closed loop system also increases"--

Book Synopsis Chaos in Switching Converters for Power Management by : Enric Rodríguez Vilamitjana
Download or read book Chaos in Switching Converters for Power Management written by Enric Rodríguez Vilamitjana. This book was released on 2012-08-14. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the need for models and techniques to predict stability boundaries, given trends toward miniaturization of switching power supplies in battery-operated portable devices, which lead to the exhibition of fast-scale chaotic instabilities. The authors describe a method to predict stability boundaries from a design-oriented perspective, which captures the effect of the different parameters of the system upon the particular boundary. Unlike previous methods involving complex analysis based on the discrete-time mathematical model, the method introduced here allows for prediction of the overall stability boundaries within the complete design space and is based upon a simple design-oriented index.

Book Synopsis Chaos Analysis and Chaotic EMI Suppression of DC-DC Converters by : Bo Zhang
Download or read book Chaos Analysis and Chaotic EMI Suppression of DC-DC Converters written by Bo Zhang. This book was released on 2015-04-30. Available in PDF, EPUB and Kindle. Book excerpt: Introduces chaos theory, its analytical methods and the means to apply chaos to the switching power supply design DC-DC converters are typical switching systems which have plenty of nonlinear behaviors, such as bifurcation and chaos. The nonlinear behaviors of DC-DC converters have been studied heavily over the past 20 years, yet researchers are still unsure of the practical application of bifurcations and chaos in switching converters. The electromagnetic interference (EMI), which resulted from the high rates of changes of voltage and current, has become a major design criterion in DC-DC converters due to wide applications of various electronic devices in industry and daily life, and the question of how to reduce the annoying, harmful EMI has attracted much research interest. This book focuses on the analysis and application of chaos to reduce harmful EMI of DC-DC converters. After a review of the fundamentals of chaos behaviors of DC-DC converters, the authors present some recent findings such as Symbolic Entropy, Complexity and Chaos Point Process, to analyze the characters of chaotic DC-DC converters. Using these methods, the statistic characters of chaotic DC-DC converters are extracted and the foundations for the following researches of chaotic EMI suppression are reinforced. The focus then transfers to estimating the power spectral density of chaotic PWM converters behind an introduction of basic principles of spectrum analysis and chaotic PWM technique. Invariant Density, and Prony and Wavelet analysis methods are suggested for estimating the power spectral density of chaotic PWM converters. Finally, some design-oriented applications provide a good example of applying chaos theory in engineering practice, and illustrate the effectiveness on suppressing EMI of the proposed chaotic PWM. Introduces chaos theory, its analytical methods and the means to apply chaos to the switching power supply design Approaches the subject in a systematic manner from analyzing method, chaotic phenomenon and EMI characteristics, analytical methods for chaos, and applying chaos to reduce EMI (electromagnetic interference) Highlights advanced research work in the fields of statistic characters of nonlinear behaviors and chaotic PWM technology to suppress EMI of switching converters Bridges the gap between numerical theory and real-world applications, enabling power electronics designers to both analyze the effects of chaos and leverage these effects to reduce EMI
