Hi all,
I add a valley fill circuit (2 nos 47mf caps and 3 nos diodes) in 30w SMPS. it workout > 0.9PF.
But in 230VAC range only it consumes more (>30%) means Very low efficiency. I also tried different mf caps but no use.I donot know the reasion, Please anybody explain the reasion and solution.
Thanks
