Download or read book Development and Analysis of High-frequency, High-density PFC Power Conversion written by Ali Saeed AlShehab and published by . This book was released on 2015 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis explores the design of power converters that deliver isolated low-voltage dc output (~24V) and operate from "universal" ac input voltage (85 - 264 Vac RMS). It is important that these converters have good overall efficiency (~90-95%), and good ac line power factor (>0.9, and ideally >0.95) to better utilize the available energy. This thesis looks into achieving high efficiency, high power factor, low voltage stresses, and smaller component sizes by utilizing high frequency operation. The research focuses on component and subsystem evaluation, development and testing as a part of many-person research in this space. The thesis presents a literature based study on current PFC circuit designs and tradeoffs. It also introduces a specific PFC architecture, which provides a low dc output voltage drawing energy from a wide range ac input voltage while maintaining a high power factor. The architecture includes two stages: The first is a "Power Factor Correction" (PFC) which functions as an input stage drawing energy from a wide-range input current. It uses a resonant transition inverted (RTI) buck converter topology to step down the voltage from line voltage (85 - 264 Vac RMS) to around 72V. Furthermore, the inductor for the RTI buck is analyzed. The middle stage is an energy buffer to provide the required energy level for twice line frequency energy buffering and 20ms of energy hold up. The capacitor requirements, analysis, and selection are explored and developed. The second stage is a transformation and regulation stage which also provides electrical isolation between the ac input and dc output. The thesis also explores the use of available conventional high-density telecom "brick" converters as a second stage. In conclusion, the project explores the possibility of using a buck configuration for the PFC, sacrificing the ability to use high energy density 400V capacitors while gaining the advantage of using the high-density telecom brick converters and different output voltage options.

Download or read book Analysis of Power Factor Correction Converters written by Thomas Yeh and published by . This book was released on 1992 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Power Converter with capacitive input filter is a non-linear load to the Utility AC power lines. There are widely used as Switch-Mode Power Supplies in office equipment applications ranging from Personal Computers to Office Printers and Copiers. The distorted input current waveform extracted by the capacitive input filter of the power converters produces unwanted harmonics which propagates to other line powered equipments. The harmonic pollutes the AC lines and interferes with the operations of sensitive line powered equipments. The distorted current waveform also leads to inefficient utilization of the available power from the AC outlet. This is because the AC line power is transferred to the load only when each frequency component of the line voltage is an in-phase, scaler related quantity with respect to the same frequency component of the extracted current. The problems of poor power factor and harmonic distortion are compounded by the proliferation of Switch-Mode power supplies and the situation is rapidly becoming intolerable. The problem of poor quality input current waveform can be described by two quantitative measurements: Power Factor (pf) and Total Harmonic Distortion (thd). Two general approaches are available to remedy the problem. One approach is to install passive filter networks between the Utility AC lines and the capacitive input filter. The second approach is to design active power processors as dedicated Power Factor Correction (pfc) Converters and installed as the front end to the capacitive input filter to shape the distorted current waveform into waveforms which will yield higher power factor. This Thesis first introduce the general concept of PF and harmonic distortion in Chapter 1. Chapter 2 derive the mathematical description of pf based on the concept of real power (pR) and apparent power (pA). Both sinusoidal and nonsinusoidal cases are studied. For comparison and completeness, two popular passive power factor correction filter networks are analyzed in Chapter 3 to derive the maximum achievable power factor for each network along with the corresponding harmonic distortions. Governing equations are derived and presented graphically as a function of the filter network and load parameters. Chapter 4 provides the analysis of active power factor correction using switch mode Boost Converter. The analysis is carried out for two types of current controllers used as the current modulators for current waveform shaping. The state space averaged modeling approach is employed to derive the mathematical model of the Boost Converter suitable for large signal time domain and small signal frequency domain analysis. The model is further extended to derive the describing equations for the Boost Converter operating as pfc converter. Characteristics of the two current controller functions impacting the pfc operation are studied to expose their relative strength and limitations. The analysis includes the supplementation of the current control loop by an outer voltage control loop to regulate the output capacitor voltage of the pfc converter. The large signal analysis is first investigated for PF, waveform quality and voltage regulation. The small signal analysis follows to extract the frequency domain behavior of the pfc Boost Converter. The limitation of the voltage control bandwidth and its effect on the achievable pf is discussed. Chapter 5 verified the analysis through computer simulation using PSPICE. The original works of Bello based on Berkeley SPICE are modified for PSPICE. The models are extended to implement the PFC control functions and simulated in both large signal time domain and small signal frequency domain. Both the analysis and computer simulation results are compared to a published design of pfc Converter."--Abstract.

This book was released on 2012-05 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Single phase high power factor rectification is the most frequently accomplished using a boost converter. The input current shaping approach results in low line currents harmonic distortion and a power factor close to unity at the interface between the ac line and the rectifier. Various techniques are available for active current shaping, average current mode control, nonlinear control and one cycle control. Most of them are now supported by dedicated integrated circuits. Average-current-mode control is the regular control where the inductor current is forced to follow the input voltage. Recently nonlinear phenomena have been obvious in AC/DC converters which results in unstable regime such as period doubling and chaos. During these operating regimes, the input current distorts and therefore, breaks the operation of PFC converters. In this book, a study for stability for the three practical controls of boost PFC converter is introduced. Each technique has been tested to determine the practical limitation for stable regions. Design guidelines are made clear for stable operation in the examined control techniques. Experimental results confirm simulation with good matching.

Available in PDF, EPUB and Kindle. Book excerpt: Unmanned aerial vehicles (UAVs) are being increasingly used in different applications in both military and civilian domains. These applications include surveillance, reconnaissance, remote sensing, target acquisition, border patrol, infrastructure monitoring, aerial imaging, industrial inspection, and emergency medical aid. Vehicles that can be considered autonomous must be able to make decisions and react to events without direct intervention by humans. Although some UAVs are able to perform increasingly complex autonomous manoeuvres, most UAVs are not fully autonomous; instead, they are mostly operated remotely by humans. To make UAVs fully autonomous, many technological and algorithmic developments are still required. For instance, UAVs will need to improve their sensing of obstacles and subsequent avoidance. This becomes particularly important as autonomous UAVs start to operate in civilian airspaces that are occupied by other aircraft. The aim of this volume is to bring together the work of leading researchers and practitioners in the field of unmanned aerial vehicles with a common interest in their autonomy. The contributions that are part of this volume present key challenges associated with the autonomous control of unmanned aerial vehicles, and propose solution methodologies to address such challenges, analyse the proposed methodologies, and evaluate their performance.

Download or read book Sliding Mode Control of Switching Power Converters written by Siew-Chong Tan and published by CRC Press. This book was released on 2018-09-03 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sliding Mode Control of Switching Power Converters: Techniques and Implementation is perhaps the first in-depth account of how sliding mode controllers can be practically engineered to optimize control of power converters. A complete understanding of this process is timely and necessary, as the electronics industry moves toward the use of renewable energy sources and widely varying loads that can be adequately supported only by power converters using nonlinear controllers. Of the various advanced control methods used to handle the complex requirements of power conversion systems, sliding mode control (SMC) has been most widely investigated and proved to be a more feasible alternative than fuzzy and adaptive control for existing and future power converters. Bridging the gap between power electronics and control theory, this book employs a top-down instructional approach to discuss traditional and modern SMC techniques. Covering everything from equations to analog implantation, it: Provides a comprehensive general overview of SMC principles and methods Offers advanced readers a systematic exposition of the mathematical machineries and design principles relevant to construction of SMC, then introduces newer approaches Demonstrates the practical implementation and supporting design rules of SMC, based on analog circuits Promotes an appreciation of general nonlinear control by presenting it from a practical perspective and using familiar engineering terminology With specialized coverage of modeling and implementation that is useful to students and professionals in electrical and electronic engineering, this book clarifies SMC principles and their application to power converters. Making the material equally accessible to all readers, whether their background is in analog circuit design, power electronics, or control engineering, the authors—experienced researchers in their own right—elegantly and practically relate theory, application, and mathematical concepts and models to corresponding industrial targets.
