Hi all
I have a project where I need to provide +/- DC rails @ around 50V.
I will be going for a linear design, for simplicity with a toroidal transformer (unless you believe this is a stupid idea and I am not "up" on the latest switching technology".)
Desired performance criteria;
+/- 50V rails
10A per rail
Regulated, smoothed output
I thought this would be simpler than it is! My thoughts were to use a linear regaultor to regulate that unregulated 50V +/- 20% DC coming from the transformer/recitifer/filter stage but quickly I have realised there are no "off the shelf" IC's to do this (unless I am missing them) and the power loss even if only 5V is dropped across the linear regaultor will be 50W! thats hot!
I do not care about efficiency, I just need a nice 50V DC rail.
Any guidance on a topology to use for this would be greatly appreciated.
Thanks
