Answer / pritish

Deal all
we know the input to the rectifier is ac and output is dc so it is not possible to calculate the power factor in conventional analysis abecause the source ttransformer oor tthe supply contains iharmonics aand hence we cannot determine tthe supply actual angle between tvoltage and current.
Hence the power factorfactor canbe calculated aas input power frfactor which is the product of adisplacement efactor and distortion factor.

Answer / vivek aghera

I don't know it's right or wrong,,
Bt use two rectifier(one is inverter) one use for convert in dc and other convert that into ac then compare input and output and then use of this calculate efficiency.

difference between ac series and parallel circuit
