However, SMPS operate at high switching frequencies, and the associated transient pulses are full of highfrequency harmonics that may cause electromagnetic interference (EMI).
然而，由于开关电源工作在高频状态，其产生的瞬态脉冲包含有能够发射电磁干扰(emi)的的高频谐波。

According to features of power quality disturbance signal, this paper detects the disturbance signals of high-frequency, transient impulse and voltage notch with wavelet transforming.
