Book Synopsis High-performance Single-phase Line-interfaced Power Converters by : Danish Shahzad
Download or read book High-performance Single-phase Line-interfaced Power Converters written by Danish Shahzad and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of single-phase line-interfaced power converters in electrical power systems is rapidly growing due to the changing nature and power quality requirements of electrical loads. Most applications require these single-phase line-interfaced power converters to be compact and efficient, and depending on application meet additional performance, cost, and reliability targets. This thesis presents innovative system architectures, circuit topologies, design methodologies, and control strategies for highly compact and efficient single-phase ac-dc and ac-ac line-interfaced power converters. First, a comprehensive design methodology for step-down isolated two-stage ac-dc converters is presented which compares various designs and operating modes and selects the optimal design based on overall volume and efficiency. Additionally, a new control strategy is presented for a compact front-end soft-switched power-factor correction (PFC) stage to ensure compliance with strict electromagnetic interference (EMI) regulations. A 1-kW universal-input to 28 V-output isolated ac-dc prototype converter is built to showcase performance benefits of proposed design and control strategies. This prototype achieves a high-power-density of 84W/in3 and maintains greater than 93% efficiency across a wide output power range. Next, the functionality of the proposed ac-dc converter is further enhanced by incorporating a new droop control strategy for parallel operation of multiple similar ac-dc converter modules. The proposed control strategy uses the input current of the secondary dc-dc stage of two-stage ac-dc converters in conjunction with variable droop resistance to achieve near-perfect parallel operation. A multi-module ac-dc conversion system is built to validate the proposed droop control strategy. The parallel modules achieve a current distribution error of less than 2% near their maximum output power. Multiple ac-ac conversion applications are also addressed in this thesis. For highly cost-sensitive applications, two compact and efficient single-stage ac-ac converters are presented which utilize a comprehensive design methodology centered around minimizing the total cost of components. Moreover, innovative control strategies are presented for both ac-ac converters to enable output voltage regulation under input voltage and output load fluctuations. Both single-stage ac-ac prototype converters, utilizing the proposed design and control strategies, are built and tested. The 600-W 480 Vrms to 264 Vrms prototypes achieve power densities exceeding 40W/in3 while maintaining conversion efficiencies of greater than 96% across majority of the output load. Finally, a much more feature-rich ac-dc-ac converter is also proposed for advanced ac-ac conversion applications, such as data center online uninterruptible power supplies (UPS). The proposed transformer-less two-stage ac-ac converter is based on a new circuit topology which can operate at high switching frequencies (up to several MHz) and utilize 50% lower dc-bus capacitance than conventional split-dc-bus topologies. A 1-k VA 120 Vrms prototype ac-dc-ac converter is built and extensively tested to showcase performance improvements. This prototype achieves high peak conversion efficiency of greater than 95% and high power density of 26.4W/in3 while utilizing long-life but relatively bulky film dc-bus capacitors.

Book Synopsis Advanced Concepts for Renewable Energy Supply of Data Centres by : Jaume Salom
Download or read book Advanced Concepts for Renewable Energy Supply of Data Centres written by Jaume Salom and published by River Publishers. This book was released on 2017-06-12 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid increase of cloud computing, high performance computing (HPC) and the vast growth in Internet and Social Media use have aroused the interest in energy consumption and the carbon footprint of Data Centres. Data Centres primarily contain electronic equipment used for data processing (servers), data storage (storage equipment), and communications (network equipment). Collectively, this equipment processes, stores, and transmits digital information and is known as information technology (IT) equipment. Advanced Concepts for Renewable Energy Supply of Data Centres introduces a number of technical solutions for the supply of power and cooling energy into Data Centres with enhanced utilisation of renewable energy sources in order to achieve low energy Data Centres. Because of the high energy density nature of these unique infrastructures, it is essential to implement energy efficiency measures and reduce consumption before introducing any renewable energy source. A holistic approach is used with the objective of integrating many technical solutions such as management of the IT (Information Technology) load, efficient electrical supply to the IT systems, Low-Ex air-conditioning systems, interaction with district heating and cooling networks, re-use of heat, free cooling (air, seawater, groundwater), optimal use of heat and cold storage, electrical storage and integration in smart grids. This book is therefore a catalogue of advanced technical concepts that could be integrated into Data Centres portfolio in order to increase the overall efficiency and the share of renewable energies in power and cooling supply. Based on dynamic energy models implemented in TRNSYS some concepts are deeply evaluated through yearly simulations. The results of the simulation are illustrated with Sankey charts, where the energy flows per year within the subsystems of each concept for a selected scenario are shown, and graphs showing the results of parametric analysis. A set of environmental metrics (as the non-renewable primary energy) and financial metrics (CAPEX and OPEX) as well of energy efficiency metrics like the well-known PUE, are described and used to evaluate the different technical concepts.
