Koperfoliewindingen

Koperfoliewindingen are electrical windings made from thin copper foil strips used in transformers, inductors, and electromagnetic components. These windings offer advantages over traditional round wire windings, particularly in high-frequency applications where reduced skin effect and lower AC resistance are beneficial. The manufacturing process involves precisely cutting copper foil to specific dimensions and winding it around a core or former. The foil's rectangular cross-section allows for higher fill factors, leading to more efficient electromagnetic coupling and better space utilization. Copper foil windings excel in thermal management due to their flat surface, which facilitates effective heat dissipation. They are commonly found in switch-mode power supplies, RF transformers, and induction heating equipment. The use of copper foil instead of round wire minimizes proximity effects and reduces overall winding resistance, making these windings particularly suitable for high-power, high-frequency applications where efficiency and performance are critical.
