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
