Abstract: It is well-known that the high-performance polymeric dielectric films used for high-voltage DC capacitors should have outstanding capabilities in terms of electrical and mechanical properties in order to face harsh operating conditions. Many factors limit the ability of these thin films to face different and growing stresses according to modern electrical requirements. Microstructure properties, additives, impurities, defects formed during manufacturing as well as applied stress types significantly affect the … Show more

“…DC breakdown voltage largely depends on the lm quality, such as surface roughness, chemical defects, and physical impurities. 30,31 Therefore, a large distribution of data points was taken using a Weibull statistical analysis to check their failure probability to assess the effect of extrinsic factors like dust, residual solvent, small molecules, and crystallization, which are responsible for lower probability breakdown, as shown in Fig. 4.…”

“…The term of self-healing or clearing phenomena is used for a MIM structure to qualify its ability to self-repair and recover its capacitor behavior after a breakdown [22]. A consequence of the self-healing phenomena is a decrease of the effective area of the metallic electrode and then a decrease of the capacitance.…”

“…As an insulation material, PP film has a dominant influence on the insulation properties of power capacitors [ 6 , 7 ]. In the long-term operation process, the breakdown of PP film affected by the electrothermal field leads to a decrease in capacity and lifetime, which is an important cause for the failure or even explosion of power capacitors [ 8 , 9 ]. The molecular chains of PP break and become small molecular products, leading to the formation of low-density regions, where collision ionization occurs and eventually leads to the breakdown of PP film [ 10 ].…”
