This book was released on 2019 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of Photo Voltaic (PV) systems in battery charging applications has been on the rise for the past decade. A PV module generates direct current and relatively low voltage; this voltage needs to be increased and stabilized using a DC-DC converter before charging a battery load. Due to the intermittent nature of the PV system, the input voltage varies with respect to weather conditions; therefore, it is vital to control and adjust the output voltage. In this work, we first utilize a switch-mode DC-DC boost converter with a proposed feedback control for a solar battery charging system. A fixed frequency compensated voltage- mode controller is designed and implemented for a DC-DC boost converter operating in Continuous Conduction Mode (CCM). Secondly, we design a full-wave quasi resonant DC-DC boost converter, as a softswitching technique, to increase the efficiency of DC- DC converter by reducing the switching losses is proposed. To achieve the soft switching functionality for the DC-DC boost converter, and to regulate a stable output voltage, a frequency control technique is proposed in this work. The proposed control strategy justifies both frequency and the duty cycle of the Pulse Width Modulated (PWM) control signal, which in turn controls the switching of the converter's switches. Finally, an interleaved DC-DC quasi-resonant boost converter for PV based battery charging is proposed to increase the efficiency of the battery charger system by reducing the ripple across the battery load. The topology of the circuit implements a Maximum Power Point Tracking (MPPT) algorithm at a specified solar irradiation. The control technique proposes a solution to obtain maximum voltage using Perturb and Observation (PO) method, obtains a conversion ratio for the converter topology, and applies frequency modulation to regulate the output voltage in order to design a robust charger. Matlab Simscape toolbox is used to conduct the simulation studies evaluating the performance of the proposed circuit topologies and controllers for a PV-based battery charging system.

This book was released on 2012-03-30 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increased efficiency and quality constraints imposed on electrical energy systems have inspired a renewed research interest in the study of formal approaches to the analysis and control of power electronics converters. Switched systems represent a useful framework for modeling these converters and the peculiarities of their operating conditions and control goals justify the specific classification of “switched electronic systems”. Indeed, idealized switched models of power converters introduce problems not commonly encountered when analyzing generic switched models or non-switched electrical networks. In that sense the analysis of switched electronic systems represents a source for new ideas and benchmarks for switched and hybrid systems generally. Dynamics and Control of Switched Electronic Systems draws on the expertise of an international group of expert contributors to give an overview of recent advances in the modeling, simulation and control of switched electronic systems. The reader is provided with a well-organized source of references and a mathematically-based report of the state of the art in analysis and design techniques for switched power converters. Intuitive language, realistic illustrative examples and numerical simulations help the reader to come to grips with the rigorous presentation of many promising directions of research such as: converter topologies and modulation techniques; continuous-time, discrete-time and hybrid models; modern control strategies for power converters; and challenges in numerical simulation. The guidance and information imparted in this text will be appreciated by engineers, and applied mathematicians working on system and circuit theory, control systems development, and electronic and energy conversion systems design.

Book excerpt: POWER CONVERTERS, DRIVES AND CONTROLS FOR SUSTAINABLE OPERATIONS Written and edited by a group of experts in the field, this groundbreaking reference work sets the standard for engineers, students, and professionals working with power converters, drives, and controls, offering the scientific community a way towards combating sustainable operations. The future of energy and power generation is complex. Demand is increasing, and the demand for cleaner energy and electric vehicles (EVs) is increasing with it. With this increase in demand comes an increase in the demand for power converters. Part one of this book is on switched-mode converters and deals with the need for power converters, their topologies, principles of operation, their steady-state performance, and applications. Conventional topologies like buck, boost, buck-boost converters, inverters, multilevel inverters, and derived topologies are covered in part one with their applications in fuel cells, photovoltaics (PVs), and EVs. Part two is concerned with electrical machines and converters used for EV applications. Standards for EV, charging infrastructure, and wireless charging methodologies are addressed.

This book was released on 2022-02-16 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to present some advanced control methodologies for power converters. Power electronic converters have become indispensable devices for plenty of industrial applications over the last decades. Composed by controllable power switches, they can be controlled by effective strategies to achieve desirable transient response and steady-state performance, to ensure the stability, reliability and safety of the system. The most popular control strategy of power converters is the linear proportional–integral–derivative series control which is adopted as industry standard. However, when there exist parameter changes, nonlinearities and load disturbances in the system, the performance of the controller will be significantly degraded. To overcome this problem, many advanced control methodologies and techniques have been developed to improve the converter performance. This book presents the research work on some advanced control methodologies for several types of power converters, including three-phase two-level AC/DC power converter, three-phase NPC AC/DC power converter, and DC/DC buck converter. The effectiveness and advantage of the proposed control strategies are verified via simulations and experiments. The content of this book can be divided into two parts. The first part focuses on disturbance observer-based control methods for power converters under investigation. The second part investigates intelligent control methods. These methodologies provide a framework for controller design, observer design, stability and performance analysis for the considered power converter systems.

Download or read book Soft Switching Converter For Photovoltaic Systems written by Prabin James and published by LAP Lambert Academic Publishing. This book was released on 2014-10-13 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-efficiency dc-dc converters with high-voltage gain have been researched due to increasing demands. Boost converter is one of the most important and widely used devices of modern power applications. They are required as an interface system between the low voltage sources and the load which requires higher voltage in many applications such as electric vehicles, uninterruptible power supplies, fuel cells, and photovoltaic systems .Till now boost converters with coupled inductors are used where switching losses are dissipated leading to higher switching losses and low overall efficiency. A conventional boost converter is often used in step-up applications due to its simple structure and low cost. However, it is not suitable for high step-up applications. Also, the severe reverse-recovery problem of the output diodes degrades system performance such as efficiency and electromagnetic noises. Boost converter with auxiliary resonant circuit can overcome these problems by either forcing current (ZCS) or voltage (ZVS) or both of them to zero. By adopting this topology the total efficiency of the system is improved. As boost converters are widely used these days therefore large amount.
