Hello guys and thank you all for your great info here, i have so much to read.

I wanted to ask you if you can give me any guidelines on what to follow, i would like to make a psu for a RF transmitter (the amplifier part of it to me more specific) which requires 50-60V and 50A (around 2.5kW)
It has to avoid inducing noise to the amplifier, have protections and maybe even fault reporting, i don't know if i need an active PFC or not.

How do i choose a transformer core (size etc) ? Which way should i go? What topology is preferred in these situations?
Which controller is suitable for an application like this??

Thank you all again
