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?

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

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
