    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?

    AM UNABLE TO FIGURE OUT transformer which I shouls use

    XFRM_NONLIN/CT-PRI this what we used

    This may not help. If not someone with knowledge of spice will need to help.
    But here is a transformer. The 220 volt side is 20H and 2 ohms, the 12 volt side is .061F and .04 ohms each. I used a coupling of 1.

    Do you know anyone who does pspice

    No, I don't, but there are probably some people here that do. If you want to change the circuit to LTSpice there are several people here that could help. It is a free download from Linear Technology.

    no sorry it should be done only in pspice

    IS THERE ANYONE WHO CAN HELP ME WITH THIS

    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.

    Take a look here: http://www.intusoft.com/articles/converg.pdf
