Abstract: In recent years, the automotive and aerospace industries have brought stringent reliability constraints on power electronic converters because of safety requirements. Today power electronic products expect up to 20 years of lifetime in some cases even longer and they are expected to have a failure free period. The renewable energy sectors are following the same trend, and more and more efforts are being devoted to improving power electronic converters to account for reliability with cost-effective and sustainable solutions. This presentation will introduce the recent progress in the reliability aspect study of power electronic converters. It will cover: the motivations for highly reliable electric energy conversion in energy systems; reliability requirements and its implication on the power electronic converters; failure mechanisms and lifetime models of key power electronic components; system mission profiles; reliability analysis methods and tools, which can be used to design for reliability. A case of a solar park will be given at the end.
