Available in PDF, EPUB and Kindle. Book excerpt: "This dissertation presents a comprehensive study of Dual Active Bridge (DAB) converters for Solid State Transformers (SSTs). The first contribution is to propose an ac-ac DAB converter as a single stage SST. The proposed converter topology consists of two active H-bridges and one high-frequency transformer. Output voltage can be regulated when input voltage changes by phase shift modulation. Power is transferred from the leading bridge to the lagging bridge. It analyzes the steady-state operation and the range of zero-voltage switching. It develops a switch commutation scheme for the ac-ac DAB converters. Simulation and experiment results of a scaled down prototype are provided to verify the theoretical analysis. The second contribution is to develop a full-order continuous-time average model for dc-dc DAB converters. The transformer current in DAB converter is purely ac, making continuous-time modeling difficult. Instead, the proposed approach uses the dc terms and 1st order terms of transformer current and capacitor voltage as state variables. Singular perturbation analysis is performed to find the sufficient conditions to separate the dynamics of transformer current and capacitor voltage. Experimental results confirm that the proposed model predicts the small-signal frequency response more accurately. The third contribution addresses the controller design of a dc-dc DAB converter when driving a single-phase dc-ac inverter. It studies the effect of 120 Hz current generated by the single-phase inverter. The limitation of PI-controller is investigated. Two methods are proposed to reduce the voltage ripple at the output voltage of DAB converter. The first method helps the feedback loop with feedforward from inverter, while the second one adds an additional resonance controller to the feedback loop. Theoretical analysis, simulation and experiment results are provided to verify the effectiveness of the proposed methods"--Abstract, leaf iii.

The main aim of this book is to highlight and address recent breakthroughs in the range of emerging applications in power electronics and in harmonic and electromagnetic interference (EMI) issues at device and system levels as discussed in robust and reliable power electronics technologies, including fault prognosis and diagnosis technique stability of grid-connected converters and smart control of power electronics in devices, microgrids, and at system levels.
Book Synopsis Analysis, Optimization and Control of Grid-Interfaced Matrix-Based Isolated AC-DC Converters by : Jaydeep Saha
Download or read book Analysis, Optimization and Control of Grid-Interfaced Matrix-Based Isolated AC-DC Converters written by Jaydeep Saha and published by Springer Nature. This book was released on 2022-11-05 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents novel contributions in the development of solid-state-transformer (SST) technology both for medium-voltage (MV) and low-voltage (LV) utility grid interfaces, which can potentially augment the grid modernization process in the evolving power system paradigm. For the MV interface, a single-stage AC-DC SST submodule topology has been proposed, and its modulation and soft-switching possibilities are analysed, experimentally validated and adequately benchmarked. A control scheme with power balance capability among submodules is developed for MV grid-connected single-stage AC-DC SST for smooth operation under inevitable parameter drift scenario, and experimental validation shows excellent performance under drastic load change conditions. A novel machine learning-aided multi-objective design optimization framework for grid-connected SST is developed and experimentally validated, which equips a power electronics design engineer with meagre computational resources to find out the most optimal SST design in a convenient time-frame. This book has also contributed towards the development of dual-active-bridge (DAB)-type and non-DAB-type LV grid-interfaced isolated AC-DC converters by providing solutions to specific topology and modulation-related shortcomings in these two types of topologies. A comprehensive comparison of the DAB and non-DAB-type LVAC-LVDC converters reveals the superiority of DAB-type conversion strategy.

Book Synopsis Contributions to the Modulation and Closed-loop Control of Multilevel Dual-active-bridge Dc-Dc Converters by : Àlber Filbà Martínez
Download or read book Contributions to the Modulation and Closed-loop Control of Multilevel Dual-active-bridge Dc-Dc Converters written by Àlber Filbà Martínez and published by . This book was released on 2017 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Galvanically-isolated bidirectional dc-dc converters (IBDCs) have recently received more attention due to its increasing use in systems requiring energy transfer between two dc networks in both directions, requiring galvanic isolation and a high voltage gain. Some of these systems are energy storage systems, vehicle-to-grid power interfaces, fuel cell energy systems, uninterruptable power supplies, high-voltage dc links for electric-energy transmission, and solid-state transformers.The most prominent IBDC, thanks to its good performance, is the dual-active-bridge (DAB) converter. It features a high power density, a wide dc-voltage gain working range, a low count of passive components, and an exceptional transformer utilization. Nevertheless, the DAB converter suffers from a significant performance deterioration when operating at conditions different from its nominal design working point. This problem has been alleviated by designing complex modulation schemes, which require a high computational effort and are highly dependent on the parasitic-component values. On the other hand, as DAB converters have been lately introduced in high-power applications, higher voltages are needed in the dc links in order to achieve reasonable efficiency values. This has led to the use of multilevel topologies on the DAB converters, mainly multilevel neutral-point-clamped (NPC) topologies. However, the little and recent literature in this topic have not fully explored the operational capabilities and performance benefits of multilevel DAB converters.The aim of this thesis is to study the viability of multilevel NPC DAB (ML-DAB) converters, where the major faced challenge is the dc-link capacitors voltage balancing. First, three particular ML-DAB converters are studied, with the same number of levels on each side; the three-level, four-level, and five-level topologies (3L-DAB, 4L-DAB, and 5L-DAB, respectively). Suitable switching sequences, modulation schemes, and control schemes are designed for the proposed ML-DAB converters. The converter switching and conduction losses are studied with three figures of merit, resulting in a set of practical solutions that define the modulation parameters and achieve satisfactory converter-performance figures. These results are then generalized to the N-level topology (NL-DAB). Finally, the feasibility of ML-DAB converters with an asymmetric number of levels is also demonstrated.

This book was released on 2023-03-06 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the optimum design of the DCT in a hybrid AC/DC microgrid, which takes into account not only the influence of different inductors/capacitors values, but also numerous design goals (i.e., VCG, efficiency, stability and so on). This book examines the DCT's design problem in detail. It begins by reviewing existing DCTs in, the hybrid AC/DC microgrid and their design problems. Following that, this book proposes a family of DCT optimization design approaches to ensure that the designed DCT has good power transmission and voltage regulation ability in the hybrid AC/DC microgrid, even when the actual inductors/capacitors values fluctuate with practical power and temperature. Following that, this book provides a family of multi-objective optimization design methodologies for the DCT to guarantee that it concurrently achieves the requirements of VCG, efficiency, and system stability. This book also covers how to control the DCT in a hybrid AC/DC microgrid optimally and generically.
