Hi shurs,

I am a newbie to SMPS...
I learnt that PFC can improve the efficiency of the SMPS...
Does it also reduce EMI of the SMPS?

thanks in advance

PFC is only meant to improve power factor. From an AC power distribution system perspective, having a load with a high PF improves the efficiency of power transmission. However, this transmission efficiency is completely independent of the energy efficiency of the PFC itself. Whether the PFC performs better in terms of EMI or efficiency depends on what you are specifically comparing.
