Reliability Improvement Technology for Power Converters

This bookdescribes how todesigncircuits in power electronics systemsusing a reliability approach in three-level topologies, which have many advantages in terms of the current total harmonic distortion and efficiency. Suchconverter types are increasingly used inlarge power applicationsand 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 onlythe topology, but also the fault tolerance and the reduction of the ripples and leakage.This book is aimed at advancedstudents of electrical engineering and power electronics specialists.
