Am working on the design of a power supply project that can step down the AC voltage from 240v to 85v then convert the 85 VAC to 85VDC. I have searched for a transformer that could step down this voltage but not yet found. Anyone of you who can help out?
Use the transformer with the nearest available output voltage, and design the rectifier/voltage regulator accordingly.

i have picked the transformer and now the new problem is how to know the right diode for the ful wave rectifier. I think different diodes have different ratings and there must be some suitable diodes for the 85vac to 85vdc output
Use diodes with inverse voltage > 150V and ample current rating.

do you have a sample image of how this is done? or maybe even a link to you tube video where I can get helped?
thank you for the idea. I will appreciate more support
