This book was released on 2021-04-22 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photovoltaic (PV) energy generation is an excellent example of large-scale electric power generation through various parallel arrangements of small voltage-generating solar cells or modules. However, PV generation systems require power electronic converters system to satisfy the need for real-time applications or to balance the demand for power from electric. Therefore, a DC-DC power converter is a vital constituent in the intermediate conversion stage of PV power. This book presents a comprehensive review of various non-isolated DC-DC power converters. Non-isolated DC-DC converters for renewable energy system (RES) application presented in this book 1st edition through a detailed original investigation, obtained numerical/experimental results, and guided the scope to design new families of converters: DC-DC multistage power converter topologies, Multistage "X-Y converter family", Nx IMBC (Nx Interleaved Multilevel Boost Converter), Cockcroft Walton (CW) Voltage Multiplier-Based Multistage/Multilevel Power Converter (CW-VM-MPC) converter topologies, and Z-source and quasi Z-source. Above solutions are discussed to show how they can achieve the maximum voltage conversion gain ratio by adapting the passive/active component within the circuits. For assessment, we have recommended novel power converters through their functionality and designs, tested and verified by numerical software. Further, the hardware prototype implementation is carried out through a flexible digital processor. Both numerical and experimental results always shown as expected close agreement with primary theoretical hypotheses. This book offers guidelines and recommendation for future development with the DC-DC converters for RES applications based on cost-effective, and reliable solutions.

Download or read book Soft-switched DC-to-DC Converters for Power Conditioning of Electrolyser in a Renewable Energy System written by Deepak Gautam and published by . This book was released on 2006 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Electrolyser is a part of a renewable energy system (RES) and generates hydrogen from water electrolysis that is used in fuel cells. A dc-to-dc converter is required to couple the Electrolyser to the system DC bus. This thesis presents an extensive comparison of three soft-switched high-frequency transformer isolated dc-to-dc converters for this application. It is shown that LCL-type series resonant converter (SRC) with capacitive output filter is suitable for this application. Due to the wide variation in input voltage and load current, no converter can maintain zero-voltage switching (ZVS) for the complete operating range. To overcome this problem, two new converter configurations are proposed. Proposed Configuration 1 is a two-stage boost-LCL SRC with capacitive output filter and Proposed Configuration 2 is a transient-boost dual half-bridge LCL SRC with capacitive output filter. Operating principle, design, simulation and experimental results of the newly proposed converters are also presented.

Download or read book Artificial Intelligent Techniques for Electric and Hybrid Electric Vehicles written by Chitra A. and published by John Wiley & Sons. This book was released on 2020-07-21 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electric vehicles are changing transportation dramatically and this unique book merges the many disciplines that contribute research to make EV possible, so the reader is informed about all the underlying science and technologies driving the change. An emission-free mobility system is the only way to save the world from the greenhouse effect and other ecological issues. This belief has led to a tremendous growth in the demand for electric vehicles (EV) and hybrid electric vehicles (HEV), which are predicted to have a promising future based on the goals fixed by the European Commission's Horizon 2020 program. This book brings together the research that has been carried out in the EV/HEV sector and the leading role of advanced optimization techniques with artificial intelligence (AI). This is achieved by compiling the findings of various studies in the electrical, electronics, computer, and mechanical domains for the EV/HEV system. In addition to acting as a hub for information on these research findings, the book also addresses the challenges in the EV/HEV sector and provides proven solutions that involve the most promising AI techniques. Since the commercialization of EVs/HEVs still remains a challenge in industries in terms of performance and cost, these are the two tradeoffs which need to be researched in order to arrive at an optimal solution. Therefore, this book focuses on the convergence of various technologies involved in EVs/HEVs. Since all countries will gradually shift from conventional internal combustion (IC) engine-based vehicles to EVs/HEVs in the near future, it also serves as a useful reliable resource for multidisciplinary researchers and industry teams.

Download or read book Topology and Control of Transformer-less Modular Multilevel DC-DC Converters for HVDC Grid Application written by Fei Zhang and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "A high-voltage direct current (HVDC) system is more efficient at transmitting power over long distances than a high-voltage alternating current (HVAC) system. With the increase in renewable energy integration, HVDC technology is more important for the efficient integration of distributed energy sources (DERs) into grids. The features of a modular multilevel converter (MMC) make it the topology of choice for high-power applications for HVDC systems. To interconnect DC networks with different voltage levels, a DC-DC converter is a crucial component that plays the role of the AC transformer in the AC system. This thesis focuses on the topology of a transformer-less MMC DC-DC converter for HVDC grid applications and its control strategy. The main objective of the thesis is to develop a fully switch-based MMC DC-DC topology without using a transformer or passive filters. The proposed topologies have a hybrid combination of half-bridge submodules (HBSMs) and full-bridge submodules (FBSMs). Moreover, by taking advantage of both HBSMs and FBSMs, the proposed MMC DC-DC converter has the DC fault ride-through capability, which is necessary in DC systems. A family of transformer-less hybrid MMC DC-DC converters with T-type connections is investigated. The optimal selection rules of the submodule (SM) type, based on switch utilization and DC fault blocking capability, are evaluated under different voltage conversion ratios. A modified topology is also investigated to reduce the circulating current that balances the energy between the arms, which has delta-connected FBSMs to simultaneously maintain the unity power operation of the arms with HBSMs and the DC fault ride-through capability. In addition to the topology of an MMC DC-DC converter, a control strategy based on the model predictive control (MPC) of the MMC is presented. A voltage-level based MPC is proposed to address the issue of the large computational burden of conventional MPC used in MMC applications. Instead of directly selecting the switching states, the proposed predictive control has a hierarchical structure that first selects the optimal voltage level by assuming that the capacitor voltage of all SMs is balanced and then balances the capacitor voltages by using a separate control loop. The proposed predictive control is applied to the MMC DC-DC converter to guarantee the converter's fast response during transient operation.The performance of the proposed topology and control strategy is validated using both real-time simulation and a lab-scale, experimental test bench." --

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.
