Examination of high Q factor multilayer chip inductor applied magnetic flux path control technology

open access: yesEnergy Reports, 2020
Inductors used for power supplies can be miniaturized by increasing the frequency. However, as the frequency increases, the loss in the inductor increases, which hinders the improvement of efficiency. This study suggests a flux path control technology as
