May I mark this buck, already with PFC, or not?

ontoaba · 21st February 2011, 06:14 AM

This buck converter schematic is attached here, and voltage output will be controlled through triangle generator DC level.
Is there any rules about power factor range (ie. >0.9) for any load that could be marked as already with PFC? or it just not a spike form of current is enough?

May be the question is difficult to answer, I am going to use some words instead, like "good power factor" or "refined power factor".
I am planning to use two mje13009(0.1ohm current sense) in interleaved with 80Voutput, because I don't like to make that capacitor working too hard.
