Book Description
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.

Book Description
The use of SiC-based materials in fabricating power semiconductor devices has shown more interest than conventional silicon-based. Its promising abilities to improve the performance of power electronic systems made it a valuable choice in building high power DC-DC converters. This thesis presents the design and implementation of a three-phase bidirectional DC-DC Dual Active Bridge using SiC MOSFETs. The proposed circuit is first built in Matlab for simulation analysis. Then a phase shift modulation controller is designed in Simulink to test the simulation circuit. The controls are then integrated through an FPGA to test the prototype. Simulations and experimental results are evaluated to demonstrate the functionality and performance of the proposed circuit.

Book Description
Modern semiconductor devices have reached high current and voltage levels, and their power-handling limits can be extended if they are used in multilevel converter configurations. To create high-performance and reliable control designs, however, engineers need in-depth understanding of the characteristics and operation of these topologies. Multilevel Converters for Industrial Applications presents a thorough and comprehensive analysis of multilevel converters with a common DC voltage source. The book offers a novel perspective to help readers understand the principles of the operation of voltage-source multilevel converters as power processors, and their capabilities and limitations. The book begins with an overview of medium-voltage power converters and their applications. It then analyzes the topological characteristics of the diode-clamped multilevel converter, the flying capacitor multilevel converter, and the asymmetric cascaded multilevel converter. For each topology, the authors highlight particular control issues and design trade-offs. They also develop relevant modulation and control strategies. Numerous graphical representations aid in the analysis of the topologies and are useful for beginning the analysis of new multilevel converter topologies. The last two chapters of the book explore two case studies that analyze the behavior of the cascade asymmetric multilevel converter as a distribution static compensator and shunt active power filter, and the behavior of the diode-clamped topology configured as a back-to-back converter. These case studies demonstrate how to address the associated control problems with advanced control and modulation schemes. Examining recent advances, this book provides deep insight on the design of high-power multilevel converters and their applications. It is a valuable reference for anyone interested in medium-voltage power conversion, which is increasingly being used in industry and in renewable energy and distributed generation systems to improve efficiency and operation flexibility.
