SEPIC for converting 4 v to +/- 80 V

Hello Andromeda8 

did you try LTPowerCAD?

If you open it and select "Supply design" and then give 3759 under " Find Part (####)", in the results at the bottom you get an XLS Sheet for SEPIC design.

Hello,

Thank you for your message.

When I want to selected the excel sheet I got the following answer:

Would you please let me know if this design can provide +80v and - 80 V from 11V input?

Regards 

Can you close LTPowerCAD, and restart it with "Admin" rights or "elevated" mode?

I.e. right click on the shortcut there must be one of these options:

- Run as administrator

- Run as elevated

Hello,

I selected this:

Then I got the same result:

Which LTPowerCAD Version do you have?

You can try to update the LTPowerCAD at the first openning page under "Synch/Release"

If the error is afterwards still there, sorry I do not know why your IT policy blocking the app.

Hello 

Thank you very much for your guidance.

I did the update but still I have the same issue, Would you please put the excel file (that I can not download ) in this chat?

Would you please let me know, what kind of information I can see in that excel sheet?

Regards 

Hello ,

I could finally download the excel sheet:

Based on the information I can see that this design is SEOIC and provide positive output voltage?!

What I'm looking for is to have  to make variable output from +/- 11V to +/-70 V form a 11V input, can I make it with one controller(dual-output)? otherwise if I need two controllers would you please let me know what should be the part numbers for the controllers? is there a tool that i can simulate it?
