> 950V 36uF *DC* Oh, when you rectify a voltage you get 1.41 times Vef. If you rectify by doubling, you get 2.82 times Vef. 950/2.82 is only 336Vef. You have only ~17 Joules in the cap, once per second is 16W. Assuming poor efficiency etc it is still less than 50W. A small comfy DC/DC converter will power your application easily. No iron is required. Are you sure about the cap specs ? $0.02 Peter -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
