摘要： An inductor having a coaxial structure is described. In one example, the structure of the single-turn inductor can include a conductor, an insulation layer, a shielding layer, and a magnetic core. An air duct can be located between the shielding layer and the magnetic core. The shielding layer and the magnetic core can both be connected to a ground. In one example, the single-turn inductor can include a single-layer termination structure formed on terminations of the shielding layer. In another example, the single-turn inductor can include a double-layer termination structure formed on terminations of the shielding layer. Displacement current in the single-turn inductor can be reduced using, for example, lumped equivalent circuit models, a semi-conductive shielding layer model, or a resistive layer and conductive shielding layer model.
