UCC28704: PSpice Shut down

Hi Jeremy,

Thank you for reaching out.

Please find the attached model. It runs without shutting down, but might be slow.

Hi Harish,

I don't understand your simulation, because an initial condition is set at 23V for Vout. Why did you set this value ?

Could you send me a simulation with a Vout=0 at t=0 ?

I thank you for your attention.

Hi Jeremy,

Unfortunately, I am not able to get convergence if started with initial condition of Vout=0.. Also it takes too long on my computer which eats significant memory in my computer which prevents me from doing other tasks. So running the system overnight also does not help. You might want to tune the convergence settings and try this at your end.

Thank you

Hi Harish,

Okay, but why did you set an initial condition of Vout=23V ? I tried with an initial condition of Vout=5V, but it doesn't work. Would you have a running simulation with this setting ?

Hi Jeremy,

Unfortunately, I will not be able to debug on this simulation model now as I mentioned earlier. I think you will need to optimize on the solution settings for optimization.

Thank you
