Abstract
A wavelet packet technique to extract feature of electromagnetic interferences (EMI) signals in power electronic devices is presented. This method can be used to analyze the signals with different EMI and to get the interference feature based on its energy from the wavelet packet analysis result. By using the EMI signal singularity property, an improved measure is put forward and their qualities are appraised
