Intrusiveness of Power Device Condition Monitoring Methods: Introducing Figures of Merit for Condition Monitoring

Power electronics is becoming pervasive in electricity-based applications, making power device reliability an increasingly important topic. Maintenance operations are necessary to ensure the functioning of power electronic apparatuses [1]. Guessing the time for maintenance operations is challenging due to the related tradeoff between maintenance costs and reliability improvements. Lifetime prediction techniques and condition monitoring methods (CMMs) are useful tools for determining the actual need [2].
