Hello,
I am working on smps boost converter. The problem is that after stepping up voltage and rectifying and filtering it i am getting around 500V initially but than the voltage starts decreasing every second or so and it keeps dropping, i have not connected any load yet. Kindly look into this problem
Imagine: if your TV set is broken...it makes no sense to give your neighbour's TV set to repair.
Most likely the TV set of your neighbour is good.
But your TV set has an error.
