1. [AMPS] HV Switching Supply (score: 1): Author: park@surface.kriss.re.kr (Y. Park 박용섭); Date: Mon, 1 Feb 1999 22:43:21 +0900 (KST); Maybe it's off topic, but what about 50V 50A switching PS for a solid state amp ? Amp design is pretty well known and parts can be obtained fairly easily, but PS is problematic. Take a look at http:; /archives//html/Amps/1999-02/msg00000.html (8,561 bytes)

I presume (possibly incorrectly) that it isn't going to have lots of capacity in the output like a linear supply. If so, then the feedback; /archives//html/Amps/1999-02/msg00007.html (7,846 bytes)

Since switcher technology has progressed to the point where one could actually work with SSB and CW type loads, I'm ready for either version you are proposing!
