This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation focuses on sample-data modeling for double edge current programmed mode control (DECPM) and its application to high frequency and wide range DC-DC converters. Steady state conditions and subharmonic oscillation issues for DECPM are addressed. By combining the conventional peak and valley current programmed mode control, a sample-data model for DECPM is proposed. A small signal model for DECPM is developed by deriving the modulation gains (Fm) and the sampling gains (He) for DECPM from the proposed sample-data model. The sampling frequency dependence on the duty ratio and a large current loop gain at high frequency for DECPM are emphasized. The analytical results are verified by the simulation. Finally, DECPM is proposed as a method to control the high frequency and wide range DC-DC converters. A 10MHz four switch buck boost converter is implemented with DECPM to verify the viability of its application to high frequency and wide range converters.

Book Synopsis Dynamic Analysis of Switching-Mode DC/DC Converters by : Andre Kislovski
Download or read book Dynamic Analysis of Switching-Mode DC/DC Converters written by Andre Kislovski and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most critical part of the modern switching-mode power supply is the regulated dc/dc converter. Its dynamic behavior directly determines or influences four of the important characteristics of the power supply: • Stability of the feedback loop • Rejection of input-voltage ripple and the closely-related transient re sponse to input-voltage perturbation • Output impedance and the closely-related transient response to load perturbation • Compatibility with the input EMI filter Due to the complexity of the operation of the converter, predicting its dynamic behavior has not been easy. Without accurate prediction, and depending only on building the circuit and tinkering with it until the operation is satisfactory, the engineering cost can easily escalate and schedules can be missed. The situation is not much better when the circuit is built in the computer, using a general-purpose circuit-simulation program such as SPICE. (At the end of this book is a form for obtaining information on a computer program especially well suited for dynamic analysis of switching-mode power converters: DYANA, an acronym for "DYnamic ANAlysis. " DYANA is based on the method given in this book. ) The main goal of this book is to help the power-supply designer in the prediction of the dynamic behavior by providing user-friendly analytical tools, concrete results of already-made analyses, tabulated for easy application by the reader, and examples of how to apply the tools provided in the book.
Book Synopsis Sampled-Data Modeling and Analysis of the Power Stage of PWM DC-DC Converters by :
Download or read book Sampled-Data Modeling and Analysis of the Power Stage of PWM DC-DC Converters written by and published by . This book was released on 1999 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The power stage of the PWM DC-DC converter is modeled and analyzed using the sampled data approach. The work addresses continuous and discontinuous conduction mode under voltage mode control, and continuous conduction mode under current mode control. For each configuration, nonlinear and linearized sampled-data models, and control-to-output transfer function are derived. Using this approach, both current mode control and discontinuous conduction mode can be handled systematically in a unified framework, making the modeling for these cases simpler than with the use of averaging. The results of this paper are similar to results of Tymerski, but they are presented in a simpler manner tailored to facilitate immediate application to specific circuits. It is shown how sampling the output at certain instants improves the obtained phase response. Frequency responses obtained from the sampled-data model are more accurate than those obtained from various averaged models. In addition, a new ("lifted") continuous-time switching frequency-dependent model of the power stage is derived from the sampled-data model. Detailed examples illustrate the modeling tools presented here, and also provide a means of comparing results obtained from the sampled-data approach with those obtained from averaging.

The work addresses continuous and discontinuous conduction mode under voltage mode control, and continuous conduction mode under current mode control. For each configuration, nonlinear and linearized sampled-data models, and control-to-output transfer function are derived. Use of these models for controller design is illustrated. In addition, a new continuous-time switching frequency-dependent model of the power stage is derived from the sampled-data model. Examples illustrate the increased accuracy of control design using the new power stage models.

Download or read book Sampled-Data Modeling and Analysis of Closed-Loop PWM DC-DC Converters written by and published by . This book was released on 1999 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sampled-data analysis of converters has been a topic of investigation for the past two decades. However, this powerful tool is not widely used in control loop design or in closed-loop performance validation. Instead, averaged models are typically used for control loop design, while detailed simulations are used for validating closed-loop performance. This paper makes several contributions to the sampled-data modeling and analysis of closed-loop PWM DC-DC converters, with the aim of increasing appreciation and use of the method. General models are presented in a unified and simple manner, while removing simplifying approximations present in previous work. These models apply both for current mode control and voltage mode control. The general models are nonlinear. They are used to obtain analytical linearized models, which are in turn employed to obtain local stability results. Detailed examples illustrate the modeling and analysis in the paper, and point to situations in which the sampled-data approach gives results superior to alternate methods. For instance, it is shown that the sampled-data approach will reliably predict the (local) stability of a converter for which averaging or simulation predicts instability.
Book Synopsis Modeling Uncertainties in DC-DC Converters with MATLAB® and PLECS® by : Farzin Asadi
Download or read book Modeling Uncertainties in DC-DC Converters with MATLAB® and PLECS® written by Farzin Asadi and published by Springer Nature. This book was released on 2022-06-01 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modeling is the process of formulating a mathematical description of the system. A model, no matter how detailed, is never a completely accurate representation of a real physical system. A mathematical model is always just an approximation of the true, physical reality of the system dynamics. Uncertainty refers to the differences or errors between model and real systems and whatever methodology is used to present these errors will be called an uncertainty model. Successful robust control-system design would depend on, to a certain extent, an appropriate description of the perturbation considered. Modeling the uncertainties in the switch mode DC-DC converters is an important step in designing robust controllers. This book studies different techniques which can be used to extract the uncertain model of DC-DC converters. Once the uncertain model is extracted, robust control techniques such as ∞ and μ synthesis can be used to design the robust controller. The book composed of two case studies. The first one is a buck converter and the second one is a Zeta converter. MATLAB® programming is used extensively throughout the book. Some sections use PLECS® as well. This book is intended to be guide for both academicians and practicing engineers.

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.

This book was released on 2012-12-06 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the first time in power electronics, this comprehensive treatment of switch-mode DC/DC converter designs addresses many analytical closed form equations such as duty cycle prediction, output regulation, output ripple, control loop-gain, and steady state time-domain waveform. Each of these equations are given various topologists and configurations, including forward, flyback, and boost converters. Pulse Width Modulated DC/DC Converters begins with a detailed approach to the quiescent operating locus of a power plant under open-loop. The reader is then led through other supporting circuits once again in the quiescent condition. These exercises result in the close-loop formulations of the subject system, providing designers with the ability to study the sensitivities of a system against disturbances. With the quiescent conditions well established, the book then guides the reader further into the territories of system stability where small signal behaviors are explored. Finally, some important large signal time-domain studies cap the treatment. Some distinctive features of this book include: *detailed coverage of dynamic close-loop converter simulations using only personal computer and modern mathematical software *Steady-state, time-domain analysis based on the concept of continuity of states Voltage-mode and current-mode control techniques and their differences of merits A detailed description on setting up different equations for DC/DC converters'simulation using only PC
