A Brief Introduction to the Self-healing of Metalized Film Capacitors (2)
In the previous article we focused on one of the two different mechanisms of self-healing in metalised film capacitors: discharge self-healing, also known as high-voltage self-healing. In this article we will look at the other type of self-healing, electrochemical self-healing, also often referre...Read more -
A Brief Introduction to the Self-healing of Metalized Film Capacitors (1)
The biggest benefit of organometallic film capacitors is that they are self-healing, which makes these capacitors one of the fastest growing capacitors today. There are two different mechanisms for self-healing of metalized film capacitors: one is discharge self-healing; the other is electrochemi...Read more -

Film Capacitors VS Electrolytic Capacitors in Inverters and Converters
In the traditional inverter and converter, the bus capacitors are electrolytic capacitors, but in the new ones, the film capacitors are chosen, what are the advantages of film capacitors compared with electrolytic capacitors? At present, more and more centralized and string inverters are choosi...Read more -
What is the absorption coefficient of film capacitors? Why is the smaller it is, the better?
What does the absorption coefficient of film capacitors refer to? Is the smaller it is, the better? Before introducing the absorption coefficient of film capacitors, let’s take a look at what is a dielectric, the polarization of a dielectric and the absorption phenomenon of a capacitor. ...Read more
