High Voltage Power Supply
High Voltage Power Supply
(OP)
Hi, I am trying to design a High Voltage power supply circuit that can produce 1250V @ 0.1mA. This supply has to run off a 9V battery and thus current consumption is a big problem. I was wondering if anyone had any idea of how to go about it?.
Thanks, boreholelogger

Your closest off-the-shelf supply appears to be those specifically for photomultiplier tubes. EMCO and GLHITEK have some with low unloaded input power.

Yeah so I'm going to be running on maximum current anyway by the time I include losses. I have designed a cockroft-walton voltage multiplier circuit with a HV transformer and it seems to do the job but won't run off a 9V battery for very long, not consistently anyway.
Thanks IRstuff

Also, there are some more advanced 9v batteries available that are quite expensive, but provide more energy than the usual drug-store alkaline.
If there's room, use more than one 9v battery, or use six AA cells.
