Electrically and thermally activated ageing mechanisms in metallised polymer film capacitors
thesis
posted on 2018-07-12, 14:21 authored by Yuen-Pen LeeThis dissertation describes a combined computational and experimental study to
understand the fundamental electrostatic, thermal, electromagnetic, and discharge
related processes during the ageing of metallised polymer film capacitors. In the event
of internal breakdowns, these capacitors are capable of "self-healing" through a
controlled isolation of defects on the electrode surfaces by mosaic patterning the
electrode. The objective of this project is to develop viable computer models to
unravel electrothermally activated ageing processes in capacitors.
To provide the necessary validation to any capacitor models developed, our work is supported by comprehensive experiments including industrial standard accelerated life
tests and associated breakdown damage analyses of tested capacitors. [Continues.]
