Not really - all SMPS supplies work on the same principle - bung some current though an inductor, turn it off, store the collected HV pulse, do it again (probably at around 60kHz or so - just the right frequency to annoy MSF Rugby etc. Used to be transmitted from Rugby, now Anthorn - http://www.npl.co.uk/science-+-technology/time-and-frequency/time/msf-antenna ). I have used Murata BNX002s (http://uk.farnell.com/murata/bnx002-01/ filter-dc-power-10a/dp/9526943?Ntt=bnx002) with some success... > Will mechanical shielding be of any help with a SMPSs above? Yes, as will filtering of both the input & output power. It may not be enough though as subtle issues, such as the ground plane layout, also have a big influence... Make a box out of FR4 and solder all the seams... use RF feedthroughs for the power connections and have a BNX002 on both the input & output.... > What is the quietest HV PS design of any description? Linear, i.e. a transformer. Nick -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To post to this group, send an email to [email protected].
