Description

Technical Field

[0001] This utility model relates to the field of coil frame technology, specifically to a coil frame with an open center structure. Background Technology

[0002] In the field of power electronics, resonant inductors play a crucial role in many circuits such as switching power supplies and inverters.

[0003] Traditional resonant inductors typically employ a closed magnetic core structure. During operation, the magnetic core generates a large amount of heat due to hysteresis and eddy current losses. Since the magnetic core is enclosed, heat dissipation is severely hindered, and the heat can only accumulate in a limited space. Prolonged exposure to high temperatures will accelerate the aging of the magnetic core insulation material, reduce its insulation performance, increase the risk of short circuits and other faults, and seriously threaten the stability and reliability of equipment operation.
