Recent discussion of use of a filter choke with a battery powered K3 prompts my question in another application. I have a 50vdc 50amp switching PS which will power a 1100w sspa. Output filtering may be needed to suppress switching impulses on the 50vdc output. I have a large filter choke that was used in a 3000v PS which is probably at least 5-8Hy. Do I need a bleeder resistor across it for protecting circuits when powering off the switching PS? Or is using the large filter choke not a good idea at all. What size filter chokes would be recommended? The 50v PS is a HP PS intended for telephone industry (51v).
