AI Technical Summary
The electromagnetic interference between the core and winding of existing EE-type transformers under high-frequency operating conditions, especially magnetic field leakage and common-mode noise propagation, makes it difficult to optimize electromagnetic compatibility and withstand voltage performance in a coordinated manner.
Flexible Teflon shielding sleeves are used to cover the winding leads. Combined with the slots and creepage baffles at the bottom of the frame, the electric field coupling path is blocked and the magnetic field leakage is constrained. At the same time, the impregnation layer fills the gap between the winding and the magnetic core to improve the insulation reliability.
It improves the electromagnetic compatibility of the equipment, reduces spatial radiation interference under high-frequency operating conditions, and enhances the withstand voltage performance while strengthening the shielding effect, thus resolving the contradiction between shielding and withstand voltage and adapting to the application requirements of high-frequency and high-reliability scenarios.
