Working Principle

The working principle of aluminum-polymer capacitors is based on the principles of dielectric polarization. In electrical or electronic equipment, metal plates are arranged in parallel with a dielectric layer between them. This dielectric layer consists of an aluminum oxide layer and a polymer layer. The oxide layer helps to increase the dielectric strength and reduces the leakage current, while the polymer layer acts as an insulator to reduce capacitance losses.

During operation, a voltage is applied to the metal plates, which causes a polarization of the dielectric. This polarization causes the charge carriers in the dielectric layer to be attracted to the metal plates. This creates an electric field which stores energy and is used to pass energy between the metal plates. This electric field has a capacitance value and can be used to store energy or power electronics.
