| Abstract |
This paper presents theoretical estimation of the conducted
electromagnetic interference (EMI) from a dc-dc
switched-mode power converter, based on Fourier analysis. The
theory is applied to a buck converter. The comparison between
the theoretically estimated and measured EMI shows that the
common-mode (CM) EMI was well predicted. Up to 10 MHz the
measured differential-mode (DM) noise was much lower than
the predicted one, which could be because of unknown DM
noise source impedance. Further research is needed to find out
whether a proper model of the noise source impedance can improve
the accuracy of the DM EMI prediction. |
