Power supply ringing

Hi guys,

I modeled a PS with tube rectification that I wanted to modify to use SS.

I set the current taps to consume nothing for a couple of seconds, then the full current, to simulate tube conduction once hot.
Then you run the simulation long enough, in my case 10 seconds and check the voltage at C2, C3 and C3 (B+, B+1, B+2).

By doing this, I could see that the capacitor C3 had a 520VDC applied for a second or so at startup.
In my original design I had this cap at 500V which was not sufficient. A 600V value will be used.
And I could not see ringing of some sort: great !

I also had to tweak R1 to have B+2 and B+3 in line with the original values. The simulation gave me a 5.6K value.

I did a real life test and the results were spot on. All worked as the simulation said.

This is a great tool

A big thank you to the owner.
