Part Number: PSPICE-FOR-TI

Hi all

what is "ERROR(ORPSIM-16296): Invalid Expression: Specify either current(I) or voltage(V)."

Is there an established circuit that contains ACF Forward and IC UCC2897A ,Thanks.

  • Micky,

    Thanks for your interest in UCC2897A and TI here. Can you attach your simulation file? I'll assign to an apps engineer to support your questions.

    Regards,

    John

    Hi John,

    This is the file I downloaded. Can I modify this file to the voltage and current I want?

    Thanksslum429.zip

    Hi,

    You can modify either voltage or current but if your modification is outside of the existing design can do then you need to modify associated component values together.

    Hi Hong,

    OK, in addition, is there a way to modify the simulation time, or can I close the values that do not need to be displayed, because the simulation time is too long, 

    Thanks

  • In reply to Micky Shih:

    Hi,

    Yes, you can do these. You need to follow what PSpice instructions how to do them. 

  • In reply to Hong Huang:

    Hi Hong, 

    But he didn't let me modify the simulation time, it seems to be locked, can I provide more detailed information, 

    Thanks

  • In reply to Micky Shih:

    Hi,

    You need to save the project to a new one, such as to a new folder from PSprice. Then you can change the simulation time.

  • In reply to Hong Huang:

    Hi Hong,

    OK, I will try it.

    May I only display the voltage and current of the installed probe, and not display the other ones that are not installed, so that the simulation can run faster.

    Thanks

  • In reply to Micky Shih:

    These should be your options.

  • In reply to Hong Huang:

    Hi Hong,

    Where should I set up? Is it set from Simulation Setting? Is there a more detailed explanation,

    Thanks
