What's the bottom diode good for?

why this 120Vpeak and not correct 170Vpeak to get 120VAC. Why 1:3 upconversation, make it 10:1 for down converting. The place of ground could be better on secondary side. But the second diode (doesn't matter which one) is redunant. One is enough. In case of an upconversion 1kOhm will be much to small and the LED will burn. It 360Vpeak we are talking. What else, @giomix have you seen anything?

i dont know whats wrong, the oscilloscope changes values all the time.

Thats what an oscilloscope is made for, capture continues changing values. Check the lower left numeric values if they are relevant in size. You might be faked by autozoom.

hmmmmm. when i am saying changes, I meant that is stable and after 3-5 min gets crazy.

in this case your 60° phase offset does cause an inrush and negative offset voltage at secondary teansformer output. Set it back to zero degree and everything is fine. To wait for and end of inrush just takes to long in simulation.

it takes time to simulate but it has a lot of bugs.

from "stable" to "changes" to "crazy" idk

i am so tired and i am gonna loose my mind. The source it supposed to change by it self? i had it at 170v...

Many of us have been using this app for many years and can tell you that EC does have some problems stimulating certain things. Signal sources changing values on their own isn’t something I have ever struggled with, and haven’t heard of anyone else having issue with. Perhaps you’re right - get some rest 👍
