Testing Reliability of Electronic Components and Converters Is Vital for Systems [From the Editor]

In modern energy production, storage, transmission, distribution, and consumption, power electronics has been playing a crucial role. Because power converters are critical links in electrical energy systems, impacting system security, safety, energy efficiency, and cost, the reliability of power electronic components and converter systems has become very important in these applications. In short, the reliability of energy systems is completely dependent on the reliability of electronic components and power converters. Consequently, testing is now considered a vital reliability engineering tool to investigate failure mechanisms, identify weakest points, and demonstrate robustness margins in components and converters. However, reliability testing is not simple and requires time, right amount of data, state-of-the-art testing facilities, and understanding of uncertainties of failure mechanism.
