Download or read book DC-DC Converter Topologies written by Gerry Moschopoulos and published by John Wiley & Sons. This book was released on 2023-12-18 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: DC-DC Converter Topologies 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.

Download or read book Novel Bidirectional Single-phase Single-stage Isolated AC-DC Converter with PFC for Charging of Electric Vehicles written by Anant Kumar Singh and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis proposes a novel bidirectional single-phase single-stage AC-DC converter for Electric Vehicle (EV) charging application. AC side of the proposed converter consists of a current-fed half bridge converter. This is connected to the full-bridge converter on secondary side of a high-frequency (HF) transformer. Power Factor Correction (PFC) can be attained by regulating the current at the input of the ac side. In addition to that, the proposed converter achieves Zero Current Switching (ZCS) of primary side switches and zero current turn-on for secondary side devices throughout the operation without any additional components. Furthermore, a novel modulation technique and control algorithm is implemented. This ensures soft-switching throughout the operation range of the converter during bidirectional power flow. Design equations are derived to help suitable selection of components for a given specification. The proposed converter is designed for 1.5KW capacity for EV charging application. The simulation and experimental results are presented.

Available in PDF, EPUB and Kindle. Book excerpt: Nowadays, power electronics is an enabling technology in the energy development scenario. Furthermore, power electronics is strictly linked with several fields of technological growth, such as consumer electronics, IT and communications, electrical networks, utilities, industrial drives and robotics, and transportation and automotive sectors. Moreover, the widespread use of power electronics enables cost savings and minimization of losses in several technology applications required for sustainable economic growth. The topologies of DC–DC power converters and switching converters are under continuous development and deserve special attention to highlight the advantages and disadvantages for use increasingly oriented towards green and sustainable development. DC–DC converter topologies are developed in consideration of higher efficiency, reliable control switching strategies, and fault-tolerant configurations. Several types of switching converter topologies are involved in isolated DC–DC converter and nonisolated DC–DC converter solutions operating in hard-switching and soft-switching conditions. Switching converters have applications in a broad range of areas in both low and high power densities. The articles presented in the Special Issue titled "Advanced DC-DC Power Converters and Switching Converters" consolidate the work on the investigation of the switching converter topology considering the technological advances offered by innovative wide-bandgap devices and performance optimization methods in control strategies used.

Download or read book Small Signal Analysis and Control of Snubberless Naturally-Clamped Soft Switching Current-Fed PWM DC/DC Converters written by Koyelia Khatun and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power electronic is the prominent enabling technologies for the uninterruptible power supply (UPS), renewable energy sources, fuel cells, energy storage, electric transportation, electrical appliances and industrial processes. Owing to the challenges to safety, high step-up ratio, galvanic isolation, high-frequency (HF) transformer isolated topologies are introduced. Currentfed topologies offer the merits of high voltage gain, stiff input current and reduced peak currents. The major limitations of current-fed converters is the requirement of snubber circuit to clamp the turn-off voltage spike across the semiconductor devices. Passive snubbers leads to low efficiency as the energy absorbed by the clamping capacitor is dissipated in the resistor. Active-clamping results in better efficiency and simultaneously achieves zero voltage switching (ZVS) of the semiconductor devices. However, it needs floating active device(s) and high value of HF clamp capacitor for the effective voltage clamping. In addition, it suffers from the demerits of high current peak, high circulating current at light load, and reduced voltage gain. A new modulation technique was proposed to modulate secondary side controlled devices to clamp this voltage spike across the primary side devices eliminating the requirement of external snubber circuit. Steady-state analysis, power circuit design and steady-state performance have been reported for such class of snubberless naturally clamped current-fed converters. However, small signal analysis, control design, implementation, and transient/dynamic performance have not been studied yet. The objectives of this thesis are to present small signal analysis, closed loop control design, and demonstrate the transient performance through simulation and experimentation of the snubberless naturally clamped current-fed half-bridge and push-pull dc-dc converter topologies. Small signal model has been derived using state space averaging. Closed loop control design is done employing two-loop average current control. Simulation results using PSIM 11.1.64 are reported to verify the converter performance with the designed controller. Experimental results from a 250W proof-of-concept hardware prototype are demonstrated to show the transient performance of current-fed half-bridge and push-pull dc-dc converter topologies

Download or read book High-power Bi-directional DC/DC Converters with Controlled Device Stresses written by Sangtaek Han and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the research is to develop a cost-effective high-power bi-directional dc/dc converter with low total-device ratings, reduced system parasitic effects, and a wide input/output range. Additional objectives of the research are to develop a small-signal model and control methods, and to present performance characterizations. Device stresses in the proposed topology are controlled to maintain minimal levels by varying the duty ratio and phase-shift angle between the primary and the secondary bridges, which results in a low total-device rating, when compared to conventional bi-directional dc/dc topologies. In the proposed topology, soft switching, which reduces power loss, can be realized under specific operating conditions. When the condition that causes minimal device stress is satisfied, zero-voltage switching (ZVS) can be obtained. In the research, ZVS capability is explored for a wide range of voltage conditions as well as for the minimal device-stress condition. The performance characterization includes verifying the soft-switching regions and power-loss estimation. Another part of the thesis is the controller design of the converter. Small-signal models and feedback controllers are developed, and the controllers are experimentally validated. Because in the isolated high-frequency converters, transformer saturation is an important issue, a method to prevent transformer saturation is proposed and experimentally validated.

This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis deals with hybrid phase modulated converter with inductive output filter as well as capacitive output filter. The operational principles, detailed steady-state analysis for different modes of operation, detailed design procedure with an example. simulation and experimental results are presented for HPMC with inductive output filter. HPMC with inductive output filter has reduced output filter requirements and maintains ZVS for wide line and load variations. This converter suffers from duty cycle loss and output rectifier ringing requiring secondary-side snubbers and higher voltage rated rectifier diodes. To overcome this problem, a hybrid phase modulated DC-DC converter with a capacitive output filter is proposed. Different modes of operation of the proposed converter are identified and a detailed steady-state analysis for these modes of operation is presented. A design example of 200 W, 22 V to 41 V input voltage and 350 V output voltage hybrid phase modulated converter with inductive and capacitive output filter is given to present the design procedure. Simulation and experimental results obtained from the laboratory prototype are provided to verify the performance of the converter. A comparison of performance between the HPMC with inductive and capacitive output filters with standard phase-shifted PWM full bridge converter are also presented.

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
