Development of an In-Situ Detection Mechanism for Common-Mode Choke Saturation

Year: 2024

Type: conference-paper

Abstract: The saturation of the common mode chokes (CMCs) in the electromagnetic interference (EMI) filters can impair filter performance, increase EMI issues and reduce efficiency. Detecting saturation in operational conditions presents a significant challenge. Therefore, this paper proposes a method for detecting choke saturation using a three-winding configuration. One winding creates core saturation through the application of DC current, while another introduces high-frequency signals for detection by the third winding. The change in the detected signal indicates saturation. Experimental data validate the proposed detection mechanism, providing a complete understanding of its effectiveness in operating conditions.
