hi all,

i have an SMPS and i have measured the waveforms of some points at the primary side.But my question is i dont know whether the waveform i get is it the correct one because i'm using the add function of the scope. So after some advice from the members i would like to try on PSPICE.

Problem 1 :confused:: how to get the power switch PSPICE library?
Problem 2 :confused:: how to draw the switching transformer since i dont have any info or datasheet about the switching transformer on the board.

i need some advices.hope someone can help.

thank you.
