Influence of heat treatment on properties of high-current metallized film capacitors

Abstract

Metallized film capacitors are widely used for its high energy density capacity. Pulsed power systems, with its high current applications, rapid discharges, will stress the metallized film capacitors. The manufacturing process of the metallized film capacitors plays a dominant role in its performance. Currently, there are only a few studies on the performance of heat treatment for high-current metallized film capacitors in China and elsewhere. This paper discusses the influence of heat-treatment on the performance of high-current metallized film.
