Abstract :
In this paper, the single layer iron powder inductor´s general math model is studied and the model equations are derived. The simulations and measurements are processed to verify the model. The relations of the boost inductor impedance and DM noise spectrum are addressed in detail. Some suggestions on boost inductors are given to reduce the DM noise.
