One approach to minimize this impact is to filter the harmonic currents and the electromagneticinterference(EMI) produced by the power electronic loads.
减小这种影响的一个办法是，将由电力电子负载产生的谐波电流或者电磁干扰滤除。

Electromagneticinterference (EMI) in high-speed digital circuit is mainly generated by Common-mode (CM) noise, and the CM inductance is responsible for CM noise magnitude.
共模噪声是高速数字电路产生电磁干扰的主要原因，而共模电感又是共模噪声大小的决定因素。

However, SMPS operate at high switching frequencies, and the associated transient pulses are full of high frequency harmonics that may cause electromagneticinterference (EMI).
