Toroidal Inductor with Double Core and Interleaved Windings

Abstract

This invention concerns an innovative toroidal inductor design that combines dual cores and interleaved windings for improved performance. The inductor has two core sections arranged concentrically to form a toroidal shape. Each core is made of magnetic material, optimizing the magnetic flux path and minimizing core losses. Windings are inserted between the two cores, which enhances magnetic coupling and reduces leakage inductance. This configuration results in higher efficiency and improved thermal management compared to traditional toroidal inductors. This design is particularly advantageous for applications requiring high power density and low electromagnetic interference, such as in power electronics and communication systems. By using the dual core structure and interleaved windings, the inductor achieves superior electrical characteristics, making it suitable for advanced electronic devices and systems.
