In this article, we present the theoretical models on self-healing (SH) processes in metallized film capacitors (MFCs) in overload modes. Based on the proposed dynamic model of capacitor’s SH resistance, the current and voltage of MFC in SH process

Metallized film capacitors (MFCs) are used in many applications requiring high volumetric energy characteristics. Along with an increase in the dielectric permittivity of the polymer film, operating in overload mode is a simple way to dramatically in

A typical approach to minimizing the early failures (“infant mortality”) of the modern metallized film capacitors (MFCs) is to conduct a burn-in test at applied voltage slightly more (at 30 – 50%) than nominal value. During the test, an externa
