TINA/Spice/UCC28070: Simulation error in UCC28070.

Hi Shubham,

I observed that you have attached only .OPJ file. Could you please attach the entire project? If you have any doubt, please download any PSpice project from TI website and see what all files are there.

Thanks & Regards,

Hi Shubham,

We do not have access to Google drive. Could you please zip your entire project and attach the .zip here?

Hi arpan,

Please find the attached file.

Specification:  2.4KW, 400V output.

                       Vin: 160V to 265Vavg_boost-2019-03-27T13-10.rar

Thanks

Hi Shubham,

The issue is probably with the simulation run time set by you i.e 20ms.

By changing the run time to 1s and time step to 1u (for faster simulations) we get the following result.

 

Thanks,

Hi,

Thank You for the response, I have designed it for 400V, 2.4 KW but not able to achieve that 400V output at full load and No load.

Can you suggest the error in design?

Thank You

Hi,

Can I get to know the status of my query? I am stuck at a point and not getting where the problem is?

Thank you

Hi Shubham,

Could you please share the reference schematic you are using for getting above mentioned specification?
This will help us to look further into the issue.

Thanks,
Vivek Agarwal
