Power supply design
(OP)
am a newbie to power supply designs. I am working on a project that is involving the design of power supply system that will supply 85VDC. How do i select the transformer to step down the 240VAC in my house to 85VDC? I have searched all over the internet and i cannot find such a transformer.

If you want 85Vdc you only need:
(85Vdc / 1.41) + 1.4V = AC voltage to be rectified.
That's about 62V. Call it 65V.
Better start looking for old TV transformers. They typically had at least half a dozen secondary windings. You could usually figure out a mixture that would provide about any voltage.
