Reliability Of Power Electronic Converter Systems

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.

In modern industries, electrical energy conversion systems consist of two main parts: electrical machines and power electronic converters. With global electricity use at an all-time high, uninterrupted operation of electrical power converters is essential. Reliability in Power Electronics and Electrical Machines: Industrial Applications and Performance Models provides an in-depth analysis of reliability in electrical energy converters as well as strategies for designing dependable power electronic converters and electrical machines. Featuring a comprehensive discussion on the topics of reliability design and measurement, failure mechanisms, and specific issues pertaining to quality, efficiency, and durability, this timely reference source offers practical examples and research-based results for use by engineers, researchers, and advanced-level students.

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.

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.
