partial discharge of energy storage capacitors

By Highjoule Solar & Storage News · · >5 min read

Since insulators are always in impure form due to the presence of air bubbles/other impurities inside the insulator, local electrical breakdown called partial discharge (PD) occurs due to high voltage stresses. Failure of insulation occurs due to the presence of partial discharge.

Capacitors exhibit exceptional power density, a vast operational temperature range, remarkable reliability, lightweight construction, and high efficiency, making them extensively utilized in the realm of energy storage. There exist two primary categories of energy storage capacitors: dielectric

My question is on converting energy stored in a capacitor by engineering controlled partial discharge (leakage, etc) as an intended function of the system. I don't want to go too deep into my own thoughts on the issue Can it be done? Is there anywhere I can go to see what is being done with it? It
