Linear insulated voltage feedback

01:02:50

Hi all! I'm designing quite a lot of converters this days and while working with high voltage or generic insulated applications, i always have this problem: can a linear insulated voltage feedback be made with easy to find bjt optos like bc817? hurz made a circuit with something like this a while ago but i can't find it anymore. Does anyone have some considerations to make?

It was something with mains voltage and phase. You used two bc817 optos there

If hurz wants to put all his circuits back into public view I’m sure we will all be happy to sift through and find it for you.

I have to many circuits in privat. Its almost impossible to search within them.

It wasn't Bc817, that for sure. What you mean is probably pc817?

One of the cheapest

Yes i meant that. It can be found with different letters because a lot of manufacturers produce it
