The reliability of power electronic systems is a major concern because these systems are exposed to harsh environments, high stresses, and variable loads caused by the increasing proliferation of renewable power generation.

Real-time monitoring of aging and performance is becoming increasingly important. Monitoring the performance of power electronic devices helps identifying potential problems before they cause system failure, thus increasing the reliability and longevity of these systems.

This second edition follows new developments in converter and power electronics research and development. Coverage includes anomaly detection and prognostics, DC-link capacitors, lifetime modelling and prediction, reliability of packaging, active thermal control, test and state monitoring, stochastic hybrid systems models, wind turbine power electronics, adjustable speed drives, reliability analysis for wind and PV power, power supplies for computers, as well as high-power converters. Chapters have been carefully updated as required, and new content has been added on device-level technology.

Offering readers a deeper understanding of the components that form a power electronic system, from the device to system level, this book is aimed at researchers and research professionals across academia, industry and at grid operators, as well as senior students in the field.
