Hey,
I wanted to ask 2 questions please regarding this SMPS which contains power factor corrector.
1.
It is said in the article that the boost converter must meet with the condition that the current drawn from the line at any given instant must be proportional to the line voltage.
Why is that?
2.
It is also said that having the boost preconverter voltage higher than the input voltage forces the load to draw current in phase with the ac main line voltage that, in turn, rids harmonic emissions.
Could someone please thow light on this matter, how it brings the current and voltage to be in phase?
Thank you very much.
