Book Description

Bachelor Thesis from the year 2013 in the subject Electrotechnology, grade: Bachelor, Harbin Engineering University (College of Automation), course: Electronics, language: English, abstract: In recent years, with the development of power electronic devices control theory and the increasing demand of high-quality power supply, power electronics technology has aroused widely attention from scholars. DC-DC power converters are employed in a variety of applications, including power supplies for personal computers, office equipment; spacecraft power systems, laptop, Cell phones, and telecommunications equipment, as well as dc motor drives. In this project a detailed study of zero current switching buck converters is done and also practically implemented in hardware. In addition a mathematical analysis of switching loss occurring in MOSFET's is also presented and a short study of zero voltage switching is also appended. During the hardware implementation the Ton, Toff and operating frequency were found out and thoroughly tuned through the IC555 circuit and various waveforms across inductors, capacitors, load resistor and test points were noted down. In this thesis, the Buck type circuit structure and working principle are analyzed and a DC-DC buck converter is designed. The designed converter uses ZCS scheme and realized the function that the power form is converted from 12V DC voltages to 5 V DC voltages. The output voltage can be adjusted according to the output resistor. The output voltage is stable and the performance of the designed converter is ensured. Simulation study was carried out and effectiveness of the designed converter is verified by simulation results. Finlay design is implemented in hardware and PCB layout as well.

Book Description

Power Electronics converters used in different applications such as photovoltaic systems and electric vehicles require low size and high-efficiency converters with a step-down or step-up voltage ratio depends on their applications. Resonant switched-capacitor converters (R-SCC) are an alternative to inductor-based converters, known as buck or boost converters. These topologies reduce the size of the power converters, and their resonant operation reduces the switching losses of switching devices (higher efficiency) and mitigates the high spike-current over switching components during switching instants. In addition, DC sources are integrated into the power system through voltage-source converters (VSC). For this application, there is a need for a controller to regulate the output power and voltage of VSCs. This dissertation studies different operating modes of a multi-stage R-SCC for step-down and step-up voltage ratios. It also proposes a systematic method to calculate the output characteristics of the proposed resonant converters. In addition, a voltage controller is proposed to regulate the output voltage of the resonant converter while there is a variation in input voltage or load. It also evaluates the performance of a controller for a VSC in the VSCbased power system. All studies are verified by simulation and experimental results.

Book Description

An Integrated Power System (IPS) with a DC Zonal Electrical Distribution System (DC ZEDS) is a strong candidate for the next generation submarine and surface ship. To study the implementation of an IPS with DC ZEDS, members of the Energy Sources Analysis Consortium (ESAC) are currently constructing a reduced-scale laboratory. One fundamental component of DC ZEDS is the Ships Service Converter Module (SSCM), commonly known as a buck DC-DC converter. This thesis documents the design, simulation, construction and testing of a 500V/400V, 8kW resonant softswitched DC-DC converter. In theory, resonant converters will operate more efficiently and generate less Electromagnetic Interference (EMI) when compared to a standard hardswitched converter. In this thesis, the resonant converter is tested and compared to a hard-switched DC-DC converter that was designed for ESAC's reduced-scaled IPS. The results verify that the resonant DC-DC converter realizes significant efficiency and EMI generation improvements over the hard-switched converter at the cost of a more complex control system and power section.

Book Description

This book is devoted to resonant energy conversion in power electronics. It is a practical, systematic guide to the analysis and design of various dc-dc resonant inverters, high-frequency rectifiers, and dc-dc resonant converters that are building blocks of many of today's high-frequency energy processors. Designed to function as both a superior senior-to-graduate level textbook for electrical engineering courses and a valuable professional reference for practicing engineers, it provides students and engineers with a solid grasp of existing high-frequency technology, while acquainting them with a number of easy-to-use tools for the analysis and design of resonant power circuits. Resonant power conversion technology is now a very hot area and in the center of the renewable energy and energy harvesting technologies.

Book Description

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.
