Power electronics plays a vital role in various applications, from household devices to electric vehicles and renewable energy systems. In Denmark, the power electronics sector is a significant contributor to the economy, particularly in wind, motor, and pump controllers. This report, a result of the 4E PECTA Platform, covers reliability challenges at both component and system levels, discusses the state of the art in design processes, and proposes indicators for policymakers to support WBG adoption in energy applications. Conclusively, while existing reliability standards can partially apply to WBG semicon-ductors, the report suggests the need for specialized testing procedures and potentially international standards for ensuring their reliability. The PECTA project serves as an ideal platform for the develop-ment of such standards, involving industrial partners and research institutions with the necessary ex-pertise.
