    Re: Orcad simulation error

    I have never used Orcad, however the internet tells that you have a model issue. In the model there is an expression where division by zero happens probably.

    Similar issue: http://e2e.ti.com/support/tools/sim-...f/234/t/559783

    I recommend to use TINA-TI to simulate the converter. https://softfamous.com/tina-ti/

    Re: Orcad simulation error

    The model might not be defined for higher temperatures.. ??
