we are using PIExpert V6 for building one fly-back switching power supply, SO the calculated power supply is this kind:
and the Altium files is here:
source files are here:
So the problem is here,When we connect the 220V AC voltage source to our power supply and connect the LED lamp to output,the LED lamp becomes on for only one second and then is off (pulsing), then on then off and so on ... . So what do you think about this kind of operation causes and the way for fixing it.
And finally is there any professional software exist for simulating this kind of power supply before building it physically, we could not simulate this circuit in Altium V9 because there is no TNY280PN and the proposed transformer , so if you have simulated this kind of circuit please guide us to the correct way.(Any idea about simulating with MATLAB, PSPICE or ... and examples ).
Thanks a lot for your attention .
