Abstract Details

2022, Master of Sciences, Case Western Reserve University, Macromolecular Science and Engineering.
Power electronics have been heavily developed, with polymer film capacitors as one of the key components in power electronics. Poly(ethylene 2,6-naphthalate) (PEN) possesses the potential to be the next generation polymer film capacitor for application in the induction motor system of electric vehicles (EVs) because of its high temperature rating. Furthermore, as a result of its ability to be processed into biaxially oriented PEN (BOPEN) via tenter-line processing, BOPEN films can be both thin and uniform. In this study, the dielectric and insulating property of BOPEN is studied at different high temperatures that simulate the harsh environment in which the DC-link capacitors operate. Based on the AC/DC breakdown strength analyses and lifetime measurement, BOPEN can still operate well in high-temperature environments, even as high as 150 °C. The relationship between the semicrystalline structure of BOPEN and the insulating properties has also been studied in this thesis. Utilizing thermal annealing to increase the crystallinity (both primary and secondary crystals) and the rigid amorphous fraction, the dielectric performance of BOPEN in high-temperature environment can be even better.
