This paper deals with a method by which the experimental characterization of a power inductor is obtained from onboard measurements that exploits a low-cost DC-DC buck converter to supply the inductor under test with quasi-rectangular voltage waveforms of different amplitudes and bias conditions. The measurements of the voltage vL(t) across the inductor and the current iL(t) are performed up to inductions approaching the magnetic saturation. After suitable integration of vL(t), the magnetic flux is obtained as a function of iL and the accuracy of the described identification process is checked by comparing the measured waveform of the current to numerical simulation of the same quantity obtained assuming as input the DC current component and the measured voltage waveform.

Abstract
This paper deals with a method by which the experimental characterization of a power inductor is obtained from onboard measurements that exploits a low-cost DC-DC buck converter to supply the inductor under test with quasi-rectangular voltage waveforms of different amplitudes and bias conditions. The measurements of the voltage vL(t) across the inductor and the current iL(t) are performed up to inductions approaching the magnetic saturation. After suitable integration of vL(t), the magnetic flux is obtained as a function of iL and the accuracy of the described identification process is checked by comparing the measured waveform of the current to numerical simulation of the same quantity obtained assuming as input the DC current component and the measured voltage waveform.File | Dimensione | Formato | |
