abstract = "In recent years, power converters are increasingly moving towards high-efficiency, low losses and miniaturization. And the application of the wide-bandgap power semiconductor devices has further improved the operating frequency and efficiency of the power converter. PCB-based planar inductors are suitable for further reducing the volume of the power converter. But the increased operating frequency makes the low AC loss design of passive components at high frequency has become a bottleneck. By changing the path of leakage flux, a method of adding a low-permeability magnetic ring to the magnetic core is proposed to weak the increase in winding AC loss caused by the edge effect of the magnetic core. The results gained from the 3-D FEA simulations show that the AC resistance of the planar PCB inductor can be significantly reduced by 19.89\%.",
