This paper proposes a wavelet packet technique to analyze EMI in power electronic devices. The method can be applied to denoise and perform a feature extraction from the disturbance signal in order to identify the possible causes of the disturbance and restrain them. The simulation result is given at last, including the comparison between wavelet packet and FFT.
