Editorial for the special issue on Robust and Reliable Power Electronics

As power electronic systems are gradually gaining more and more important status in a wide range of applications, their reliability has become an important issue for the manufacturers. In recent years, the automotive and aerospace industries have brought more stringent reliability constraints on power electronic systems, because of safety requirements but also because such systems becomes much more electrified. The industrial and energy sectors are also following the same trend, and a lot of efforts are being devoted to improving power electronic systems in order to account for reliability with cost-effective combined with sustainable solutions. A paradigm shift in reliability research and engineering in power electronics is going on in terms of the design methodologies, reliability testing concepts, and robustness validation approaches [1], [2] and Fig. 1 illustrates the important aspects of modern reliability engineering in power electronics, which need to be mastered for future products.
