Metallized-film capacitors have the property, even under high continuous voltage, to self-heal i.e., to clear a defect in the dielectric. The self-healing process is a consequence of a transient arc… Proceedings of 2002 IEEE 14th International… Metallized capacitors, under high DC voltage, suffer inhibited discharges named self-healing.
Metallized film capacitors have an ability to withstand the breakdown of dielectric film due to a “self-healing” feature. The optimal design of metallized electrodes' patterns guarantees high… Owing to the property of self-healing, metalized film capacitors can be reliably used under high electric field.
To achieve such performances, metalized film capacitors (MFC) are adopted. Comparing with conventional liquid impregnant capacitors, the high energy density of MFCs is derived from the self-healing properties of metalized film.

The lifetime of MFC is closely related to the self-healing (SH) process, which causes the loss of electrode area and thus leads to the capacitance reduction. As a result, a lifetime estimation method based on the SH properties and statistics was proposed in the present study.
Owing to the property of self-healing, metalized film capacitors can be reliably used under high electric field. However, self-healing is at the expense of capacitance loss. Therefore, it is of great… Metallized film capacitors (MFCs) are used in many applications requiring high volumetric energy characteristics.
