Abstract (click to view)
Capacitors are critical for voltage source converter functionality. DC-link capacitors are known to have reliability issues. Therefore, the overall goal of this program is to improve the understanding of high voltage breakdown in high dielectric constant inorganic ceramic capacitors. This year the focus has been on improving the understanding of resistance degradation in BaTiO3 at elevated temperature, using single crystal BaTiO3 as a model system to understand the impact and control of oxygen vacancy migration to maximize the long-term reliability of high voltage inorganic multi-layer ceramic capacitors.
