The Analysis of Impedance Mismatch on the Conducted Emi Emission
نویسندگان
چکیده
This paper proposes the process to predict and analyze the conducted electromagnetic interference (EMI) emission using the impedance mismatch approach. Five steps of this process are introduced and analyzed. The impedance mismatch criterion is proposed based on current and voltage waveforms in time domain. The impedance mismatch fixtures and EMI measured results show how the relationship of impedance ratio and conducted EMI emission are occurred. This work is done using a class E zero-voltage switching (ZVS) resonant inverter at various loaded conditions: unity, lagging and leading power factors. The experimental results show some good agreements with the simulated results, which are accomplished by MATLAB program.

Prediction of the Conducted EMI from DC-DC Switched-Mode Power Converters
This paper presents theoretical estimation of the conducted electromagnetic emissions from a SMPS, based on Fourier analysis. The theory is applied to a buck converter. The comparison between the theoretically estimated and measured EMI shows that the CM EMI was well predicted. Up to 3 MHz the measured DM noise was much lower than the predicted one, which could be because of unknown DM noise so...
