hello am trying to execute this circuit in
http://www.eleccircuit.com/inverter-12v-to-220v-100w-transistor/
pspice 16.6 but we have little problem with transformer and transistors BD139 is not available in our pspice so what can we use we checked the data sheet and accordingly but we didn't get the output. am trying to uploading the pspice file but due to large data am unable to do it . not pretty sure upload_2016-2-19_17-37-24.png
this is what we designed in pspice and had problems with l1 and l2 values . please help me as soon as possible

I use LtSpice, but I think it is similar. What did you do for the transformer?

Pathuri,


There is no need to ask in capital letters, this sounds impolite.

BTW, the convergence problem you're facing is usual when dealing with simulations of power circuits in Spice, particularly due to the fact that the analysis are being done at a cicuit containing currents of very different magnitudes; In addition, the problem is exacerbated if the switching frequency is very high, because the change of values becomes smaller increasingly. In practice, this means that you will have to adjust some simulation parameters.
