A Condition Monitoring Method for Solder Layer Degradation of Liquid-Cooled Power Semiconductors
Baumann, Timm Felix; Papastergiou, Konstantinos; Murillo Garcia, Raul; Peftitsis, Dimosthenis (Chapter, 2023)This paper presents a new method for condition monitoring of solder layer degradation of liquid-cooled power semiconductors. Solder layer degradation is detected by an increased thermal impedance, which has the effect that ... -
Discharge-based condition monitoring for electrolytic DC-link capacitors
Baumann, Timm Felix; Garcia, Raul Murillo; Papastergiou, Konstantinos; Peftitsis, Dimosthenis (Journal article; Peer reviewed, 2024)Electrolytic capacitors are among the most vulnerable components in power electronic converters, risking their efficient and electrically stable operation. This is due to the decreasing capacitance under long-term stress. ... -
A quasi-offline condition monitoring method of DC-link capacitor banks in accelerator power converters
Baumann, Timm Felix; Papastergiou, Konstantinos; Raul Murillo, Murillo Garcia; Peftitsis, Dimosthenis (Chapter, 2022)This paper proposes a condition monitoring scheme for DC-link electrolytic capacitors used innregenerative medium power converters. The monitoring scheme is based on capacitor bank voltage measurements in quasi-offline ... -
Real-Time Discrete Electro-Thermal Model of Dual Active Bridge Converter for Photovoltaic Systems
Vivekanandham Pushpalatha, Yoganandam; Philipps, Daniel Alexander; Baumann, Timm Felix; Peftitsis, Dimosthenis (Journal article; Peer reviewed, 2024)Renewable energy systems have stochastic generation profiles, which affect the performance of the power electronic converters in these systems, especially due to the excessive thermal cycling. In particular, the power ...
