I've thrown together a Psu with a Sg3525 its 15v 10a and operates in half bridge.
The thing works fine.
While tuning the compensation network by connecting & disconnecting a load (halogen lamp) I accidently connected the load to the rectifier diode side of the output choke, the lamp lit but over a period of a few seconds the mains lamp I have wired in series with my isolation transformer powering the supply went from a slight glow to fully on and the supply just sat there trying to start.
I wasnt expecting that to happen, is this the transformer saturating, or a result of my pants board layout.
