This thesis proposes new power converter topologies suitable for aircraft systems. It also proposes both AC-DC and DC-DC types of converters for different electrical loads to improve the performance these systems. To increase fuel efficiency and reduce environmental impacts, less efficient non-electrical aircraft systems are being replaced by electrical systems. However, more electrical systems requires more electrical power to be generated in the aircraft. The increased consumption of electrical power in both civil and military aircrafts has necessitated the use of more efficient electrical power conversion technologies. This book presents acomprehensive mathematical analysis and the design and digital simulation of the power converters. Subsequently it discusses the construction of the hardware prototypes of each converter and the experimental tests carried out to verify the benefits of the proposed solutions in comparison to the existing solutions.

Future Naval systems and ships are being designed with pulse-power loads and hybrid electrical systems. There is a demand for efficient, reliable, and durable compact power converters to bridge pulse-power systems with the electrical plants of the future. This thesis presents modeling and analysis of a constant power Series Loaded Resonant (SLR) converter. The modeling work presented was successfully implemented in Simulink and then prototyped in a small-scale application in the laboratory. The Simulink model and prototype were tested under various conditions and may be used to reduce the risk in the design of future large-scale applications.

Numbers alone are enough to describe the importance of DC/DC converters in modern power engineering. There are more than 500 recognized topologies, with more added each year. In their groundbreaking book Advanced DC/DC Converters, expert researchers Luo and Ye organized these technologies into six generations and illustrated their principles and operation through examples of over 100 original topologies. In chapters carefully drawn from that work, Synchronous and Resonant DC/DC Conversion Technology, Energy Factor, and Mathematical Modeling provides a focused, concise overview of synchronous and multiple-element resonant power converters. This reference carefully examines the topologies of more than 50 synchronous and resonant converters by illustrating the design of several prototypes developed by the authors. Using more than 100 diagrams as illustration, the book supplies insight into the fundamental concepts, design, and applications of the fifth (synchronous) and sixth (multiple-element resonant) converters as well as DC power sources and control circuits. The authors also discuss EMI/EMC problems and include a new chapter that introduces the new concept of Energy Factor (EF) and its importance in mathematical modeling as well as analyzing the transient process and impulse response of DC/DC converters. Synchronous and Resonant DC/DC Conversion Technology, Energy Factor, and Mathematical Modeling supplies a quick and accessible guide for anyone in need of specialized information on synchronous and resonant DC/DC converter technologies.

DC/DC conversion techniques have undergone rapid development in recent decades. With the pioneering work of authors Fang Lin Luo and Hong Ye, DC/DC converters have now been sorted into their six generations, and by a rough count, over 800 different topologies currently exist, with more being developed each year. Advanced DC/DC Converters, Second Edition offers a concise, practical presentation of DC/DC converters, summarizes the spectrum of conversion technologies, and presents new ideas and more than 200 new topologies. Beginning with background material on DC/DC conversion, the book later discusses both voltage lift and super-lift converters. It then proceeds through each generation, including the groundbreaking sixth generation—converters developed by the authors that can be cascaded for high voltage transfer gain. This new edition updates every chapter and offers three new chapters. The introduction of the super-lift technique is an outstanding achievement in DC/DC conversion technology, and the ultra-lift technique and hybrid split-capacitor/inductor applied in Super-Lift Luo-Converters are introduced in Chapters 7 and 8. In Chapter 9, the authors have theoretically defined a new concept, Energy Factor (EF), researched the relations between EF and the mathematical modelling for power DC/DC converters, and demonstrated the modeling method for two converters. More than 320 figures, 60 tables, and 500 formulae allow the reader to more easily grasp the overall structure of advanced DC/DC converters, provide fast access to precise data, and help them to quickly determine the values of their own circuit components.

A resonant converter is a type of electric power converter that contains a network of inductors and capacitors called a "resonant tank", tuned to resonate at a specific frequency. They find applications in electronics and integrated circuits. The LLC resonant converter is perhaps today's most popular resonant conversion topology. Though in existence for many years, only relatively recently has the LLC resonant converter gained in popularity. Since its first appearance in the literature in 1988, for a long time it was confined to niche applications such as high-voltage power supplies or high-end audio systems. Its significant industrial usage started in mid 2000s with the boom of flat screen TVs, whose power supply requirements found in the LLC resonant converter their best answer, and was fueled by the introduction of new regulations, both voluntary and mandatory, concerning an efficient use of energy. This combination of events pushed power designers to find more and more efficient AC-DC conversion systems. Since then, several other mass-produced electronic devices, such as All-In-One and small form factor PCs, high-power AC-DC adapters and LED drivers, have made a massive usage of this topology, especially in its half-bridge version. Higher power systems, such as server and telecom power supplies and, more recently, charging stations for electric vehicles, have adopted mainly the full-bridge version. Much progress has been made on both the theoretical and practical aspects related to the LLC resonant converter. Numerous publications and application notes deal with it, and many IC manufacturers have dedicated driver ICs in their portfolio. Despite that, its design is still considered a challenging task in Power Conversion. Thus, a guided tour through its intricacies may be beneficial to both the neophyte and the experienced engineer, as well as students active in this field. This monograph covers the basics (operating modes, soft switching mechanism, first-harmonic approximation, etc.) and advanced topics (design optimization, control methods, synchronous rectification, interleaving, etc.) of power conversion using the LLC resonant converter, using a hands-on, design-oriented approach.

Presents an analysis, development of a model, and design of an experimental power supply typically used to drive high voltage and high frequency equipment. This power supply differs from conventional ones in that it used two series loaded resonant converters placed in parallel where the output voltage, the sum of both converters, is regulated shifting the voltage phase on one of the converters.
