Abstract: Power Quality (PQ) disturbances significantly impact the reliability of power electronic components, especially DC-link capacitors. However, current IEC and IEEE PQ indices do not adequately capture the effects of these disturbances, often leading to underestimated component stress.
This webinar introduces new PQ indices that better correlate real-world disturbances with capacitor heating and aging, revealing key limitations in existing standards. Further research is needed to refine these metrics and develop more accurate tools for assessing converter reliability.
The session will highlight the need to update IEC and IEEE standards to include more meaningful PQ indices, enabling more robust and reliable power electronic systems.
