One approach to minimize this impact is to filter the harmonic currents and the electromagnetic interference(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。

However, SMPS operate at high switching frequencies, and the associated transient pulses are full of high frequency 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。

Switch power of high frequency is serious electromagnetic interference (EMI) source, so EMI source filter usually should be added in switch power.

高频开关电源是严重的电磁干扰源，很多情况下需对其安装emi电源滤波器。
