AI Technical Summary

Technical Problem

Traditional magnetic core structures experience increased hysteresis and eddy current losses under high-frequency operating conditions, leading to severe heat generation and affecting the efficiency and reliability of power converters. At the same time, magnetic leakage problems affect the stability of electronic components and make it difficult to meet the requirements of miniaturization and space utilization.

Method used

The coil is mounted on the inner wall of the fixed frame and connected to the external circuit with the pins of the connector. The ferrite core is movably mounted on the inner wall of the fixed frame to form a stable magnetic circuit. Combined with the heat dissipation holes, heat conduction plate and heat sink structure, the heat dissipation effect is enhanced. The core is protected by buffer pad and anti-corrosion coating to prevent mechanical damage and corrosion.

Benefits of technology

It improves the conversion efficiency and reliability of high-frequency power converters, reduces core temperature, enhances the stability of electrical signal transmission and the compactness of the overall structure, and extends the service life of the equipment.
