Reliability Of Power Electronics Converters For Solar Photovoltaic Applications

A hands-on, case study-backed reference of control strategies, fault classification mechanisms, and reliability analysis methods for PV modules, power electronic converters, and grid-connected PV systems. Written by an international team of researchers with excellent backgrounds in academia and industry.

The main aims of power electronic converter systems (PECS) are to control, convert, and condition electrical power flow from one form to another through the use of solid state electronics. This book outlines current research into the scientific modeling, experimentation, and remedial measures for advancing the reliability, availability, system robustness, and maintainability of PECS at different levels of complexity.

The world energy demand has been increasing in a rapid manner with the increase of population and rising standard of living. The world population has nearly doubled in the last 40 years from 3.7 billion people to the present 7 billion people. It is anticipated that world population will grow towards 8 billion around 2030. Furthermore, the conventional fossil fuel supplies become unsustainable as the energy demand in emerging big economies such as China and India would rise tremendously where the China will increase its energy demand by 75% and India by 100% in the next 25 years. With dwindling natural resources, many countries throughout the world have increasingly invested in renewable resources such as photovoltaics (PV) and wind. The world has seen immense growth in global photovoltaic power generation over the last few decades. For example, in Australia, renewable resources represented nearly 15% of total power generation in 2013. Among renewable resources, solar and wind account for 38% of generation. In near future, energy in the domestic and industrial sector will become ""ubiquitous"" where consumers would have multiple sources to get their energy. Another such prediction is that co-location of solar and electrical storage will see a rapid growth in global domestic and industrial sectors; conventional power companies, which dominate the electricity market, will face increasing challenges in maintaining their incumbent business models. The efficiency, reliability and cost-effectiveness of the power converters used to interface PV panels to the mains grid and other types of off-grid loads are of major concern in the process of system design. This book describes state-of-the-art power electronic converter topologies used in various PV power conversion schemes. This book aims to provide a reader with a wide variety of topologies applied in different circumstances so that the reader would be able to make an educated choice for a given application.

This book describes how to design circuits in power electronics systems using a reliability approach in three-level topologies, which have many advantages in terms of the current total harmonic distortion and efficiency. Such converter types are increasingly used in large power applications and photovoltaics (PV), therefore research on improvements in the reliability of such systems using multi-level topologies has become important. Four studies for reliability improvement are contained in this book: an open-circuited switch fault detection scheme, tolerance control for an open-circuited switch fault, neutral-point voltage ripple reduction, and leakage current reduction. This book treats not only the topology, but also the fault tolerance and the reduction of the ripples and leakage. This book is aimed at advanced students of electrical engineering and power electronics specialists.
