Hi all,
First time posting in the forum, and a relative newbie with electronics. One of my friends is working on a mass spectrometer at school and needs help with the power supply (PS). We managed to get our hands on an older PS but it doesnt seem to work, so we are taking it apart to understand it and see if we can fabricate our own.
The circuit I have attached is what is currently in the PS, it is some type of oscillator that uses a comparator in a positive feedback configuration to generate oscillations. I was reading a bit about relaxation oscillators, which I suspect it may be, but I am a little out of my depth.
Does anyone have any ideas about the operation of this circuit? Or please let me know if I should clarify any points.
