PHF is a hybrid topology
I.e. it is connected in line with the non-linear load (VFD, UPS, and Rectifier).
PHF reduces current harmonic distortion to below 8% at full load.
PHF not only mitigates harmonics but also
Improves power factor at load end to near unity.
PHF is an effective solution for switching transients and line surges.
PHF has minimum self-losses I.e. max 1% of full load and are even less at lesser loads.
