Film Capacitors in Power Applications: Choices and Particular Characteristics Needed

The diverse collection of capacitor types has not changed much over recent years, but applications certainly have. In this article, we look at how capacitors are used in power electronics and compare the available technologies. Film capacitors are showing their advantages in upcoming applications such as electric vehicles, alternative energy power conversion, and inverters in drives. However, aluminum (Al) electrolytics are still important when energy storage density is the main requirement.
