Understanding PFC - SMPS applications


What is Power Factor Correction (PFC) PFC benets
It can be dened as the reduction of the harmonic content, Fully compliant with regional regulations imposing
and/or the aligning of the phase angle of incoming current restrictions on power factor and total harmonic distortion
PFC is required to reduce disturbance on the AC distribution (THD) in high-power applications (>75W), including:
net and maximize the real power drawn by the power supply - CCC or ‘3’C i
