Dear Mr.swapnil,
you have given the formula as P=VI*PF for both
input and output.
You should remember that the pf is not considered in the
DC (output of rectifier).
MY PROBLEM IS, OUTPUT POWER OF THE RECTIFIER IS GREATER
THAN INPUT. SO THE EFFICIENCY IS MORE THAN 100%. But the
efficiency must be with in 100%.
Any way thank you for your answer.
