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

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 DC-DC Converter Topologies by : Gerry Moschopoulos
Download or read book DC-DC Converter Topologies written by Gerry Moschopoulos and published by John Wiley & Sons. This book was released on 2024-01-31 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive look at DC-DC converters and advanced power converter topologies for all skills levels As it can be rare for source voltage to meet the requirements of a Direct Current (DC) load, DC-DC converters are essential to access service. DC-DC power converters employ power semiconductor devices (like MOSFETs and IGBTs) as switches and passive elements such as capacitors, inductors, and transformers to alter the voltage provided by a DC source into the necessary DC voltage as is required by a DC load. This source can be a battery, solar panels, fuel cells, or a DC bus voltage fed by rectified AC utility voltage. As the many components of DC-DC converters can be differently arranged into circuit structures called topologies, there are as many possible circuit topologies as there are possible combinations of circuit elements. Focusing on DC-DC switch-mode power converters ranging from 50 W to 10kW, DC-DC Converter Topologies provides a survey of all converter topology types within this power range. General principles are described for each topology type using a representative converter as an example. Variations that can be found that differ from the example are then examined, with a helpful discussion of comparisons when relevant. A broad range of topics is covered within the book, from simple, low-power converters to complex, high-power converters and everywhere in between. DC-DC Converter Topologies readers will also find: A detailed discussion of four key DC-DC converter topologies Description of isolated two-switch pulse-width modulated (PWM) topologies including push-pull, half-bridge, and interleaved converters An exploration of high-gain converters such as coupled inductors, voltage multipliers, and switched capacitor converters This book provides the tools so that a non-expert will be equipped to deal with the vast array of DC-DC converters that presently exist. As such, DC-DC Converter Topologies is a useful reference for electrical engineers, professors, and graduate students studying in the field.
Book Synopsis Design Techniques for Volume-efficient Soft-switched Power Converters with Enhanced Power Efficiency and Reliability by : Lin Cong
Download or read book Design Techniques for Volume-efficient Soft-switched Power Converters with Enhanced Power Efficiency and Reliability written by Lin Cong and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Zero voltage switching technique has been popular in high voltage DC-DC converter design to increase the switching frequency while maintaining high power efficiency and thus reducing the volume of passive components. Recently, enhancement-mode GaN FETs attracts more and more attention in high voltage converters for better figure of merits in RDSON and QG compared with the traditional MOSFETs. Although GaN FETs have been used in soft-switched DC-DC converters to further improve the power efficiency and power density, GaN FETs can cause more power loss in the third quadrant conduction than traditional MOSFETs if the dead time is not precisely controlled. In addition, fast transition of GaN FETs requires the high-voltage level shifter handle much faster dv/dt without creating logic errors. This dissertation develops a novel GaN driver with adaptive dead time control scheme, based on an innovative methodology of slope-sensing ZVS detection to minimize the third quadrant conduction time of GaN FETs. Also, a differential-mode noise blanking scheme is proposed to increase the dv/dt noise immunity of the high voltage level shifter. The proposed GaN driver can help to reduce power loss by 1.6W and achieve 90.2% power efficiency at 150V input and 2MHz frequency, or 88.6% power efficiency at 400V input and 1MHz frequency. Traditional non-isolated ZVS converters utilize an auxiliary branch to assist soft-switching operation of the active FET. In multiphase topologies or non-inverting buck-boost topology, each active power FET requires an auxiliary branch such that the total number and volume of auxiliary components make the traditional ZVS scheme infeasible. This dissertation proposes a new passive-saving technique to share one auxiliary branch between two active FETs such that the total number and volume of auxiliary components can be reduced by 50%. It is worth to notice that the proposed passive-saving technique can be applied to both ZVS and ZVT topologies. Traditional ZVT converters adopted fixed on-time of the auxiliary switch for simplicity. Since the auxiliary current ripple cannot scale with the load current, power efficiency at light load condition is quite limited. This dissertation proposes a monolithic control loop to regulate the auxiliary current ripple according to load current. Compared with the traditional ZVT converters, the proposed converter with auxiliary current control scheme can improve light load efficiency by 14.5% without folding back switching frequency.
