Sir, Please tell me that how I will calculate the efficiency of rectifier. Because input is ac and output is dc. Is it right to put two unlike signal together.

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.
