Hi Guys
well this is project number 2 - this PSU just stopped one evening after a brown out on the AC supply (tranformer somewhere died giving only 80v on the ac line)
i opened it up and discovered
1. The main fuse was blown
2. a number of swollen caps on the secondary
I thought that i measured the switching mosfet was short but it turns out its actually a diode across the mosfet that is shorted
The diode is UGK10K (http://www.datasheetarchive.com/UGP10K-datasheet.html#)
So my first question here is does anyone know of an equivalent of this diode as it doesnt seem to be available and the usuall places?
