hi all,

I have designed a smps and it is working. schematic is as attached. but i have problems of high ripples at the output..

here i have noticed that when the switching transformer is switching the shape of the primary transformer wave has ripple.

could anyone suggest a method to have a clean switching .

any comments are much appreciated
