摘要：
The EMI spectrum plays an important role in the EMC prediction of the power electronic devices. A spectrum estimation method is presented, which combines the good ability of Fourier analysis in accurate frequency localization and the features of wavelet analysis both in processing saltation signal and in adaptive processing signal, to apply a wavelet thresholding to EMI characteristic of system. This thresholding method has been verified by the simulation and the experiment results in a power converter.
