ATX Flyback Transformer
T3sl4co1l:
Well great, the schematic disappeared again.
Well, it only doesn't-work if you ground the AC source. Which I don't recall being the case, and it was also transformer isolated.
You phrased it like it's 12V DC out of the FWB, which, are you now talking about a completely different circuit? I don't follow.
Yes, you need a global ground, otherwise inverting the node matrix is equivalent to dividing by zero. Easiest way to avoid dividing by zero: put a ground somewhere useful, and don't connect capacitors in series with no resistance in parallel with them, and don't connect inductors in parallel with no resistance in series with them.

No, I'm talking about the 12VDC output voltage decaying and showing the ripple. I still have a 160VDC input to this coming out of the FWB, and a separate 9VDC source feeding only the Vcc input to the controller.
For some reason the server is giving me problems again, not allowing me to upload cuz it says the file is too big or took too long to upload.

Everything is loading fine for me and there are no errors reported on the server's end. Likely cache, browser or ISP issue. I actively monitor the server for slowdowns, network congestion, and load issues. Everything is running smoothly with good response times.

Cool, thanks.
