Power Electronics

Despite the importance of reliability in the design and control of power electronic converters, very few books have been published on this topic. The current authored in sixteen chapters by a group of authors and editors from prestigious institutes tries to fill this gap.

This book covers basic definitions and key terms in reliability engineering with a focus on their applications in power electronics converters. It briefly presents the failure mode modeling and life prediction techniques in power electronic converters. Data-driven methods for life prediction are summarized along with mathematical expressions. Reliability issues associated with the DC-link capacitor are also discussed. The packaging of power electronics converters and different methods of accelerated testing and lifetime determination in power electronics converters with a focus on mechanical stresses, vibration, and thermal tests are reviewed. There is a chapter on lifetime modeling of power electronics modules where three modeling methods i.e. thermal, empirical, and physical-based are reviewed followed by several examples. Reliability improvement, life testing, and monitoring of power modules are presented. Different stochastic reliability models, fault-tolerant adjustable speed drive systems, and reliability assessment stages including the reliability qualification plan, DFMEA ranking table, and DFMEA worksheet are among the interesting topic that readers can find in this book. In summary, this book is a valuable resource in the field of power electronics reliability offering a rich bibliography and numerous case studies. Citing industrial standards such as MLT and IEC is a prominent feature of this book which makes it useful for those working in relevant industries.
