Abstract:
The current path of the circuit is analyzed. On that basis,a new analysis model of the conducted EMI based on the drive noise is presented,which can be used to analyze the influence of the drive noise on the conducted EMI of SMPS. At the same time,experiment is conducted on the basis of the mechanical analysis. The result of experiment shows that the model and the analysis are correct and effective.
