Introduction Metallized polypropylene film capacitors (MPPFCs) offer numerous advantages, including low dielectric loss, high power density, long cycling life, rapid charge–discharge capabilities, and excellent temperature stability. These attributes make MPPFCs the preferred choice for high-voltage, high-capacity power electronic systems [1, 2].

Catastrophic failures and associated explosions or fires are unacceptable. Just as importantly, service lifetime and predictability for optimizing up-time are critical to the product's success. Film capacitors with controlled self-healing are the ideal solution to these challenges and can be obtained in various sizes and technical specifications.
Unfortunately, this mechanism can be dificult to control, and in the worst case, a run-away process can result, causing the destruction of the entire capacitor in short order. To avoid this, KYOCERA AVX developed a controlled self-healing process in 1974 based on the segmentation of overall capacitance into elementary cells protected by fuse gates.
