AI Technical Summary
Technical Problem
The magnetic core structure of existing TLVR inductors results in high mold production costs, and the lack of insulation treatment before coil assembly leads to increased product size and high power loss.
Method used
It adopts a one-piece molded fully coupled TLVR inductor structure, uses an E-type magnetic core made of iron-nickel alloy material, and has an insulating coating on the surface of the primary coil and the secondary coil. It is formed by hot pressing to form a tight fit, reducing the size and improving the magnetic saturation.
Benefits of technology
It effectively reduces the inductor volume by about 20%, reduces power loss by about 20%, and improves magnetic saturation.
