oPossum 1,083 Posted December 14, 2011 Share Posted December 14, 2011 I need a 12kv dc power source, that can supply about 10ma. I was hoping to leave inductors out of the equation also. 12 KV @ 10 mA is 120 Watts. With an efficiency of 70%, you would need about 170 Watts of power. A boost converter using an inductor is not really practical at this power level. A multiplier could be part of the solution, but only with an input that is many kV. A flyback transformer from a 19 to 27 inch TV will probably be close to what you need. The whole circuit needs to be lightweight (<2 lbs) too, Not a problem with a high frequency supply. If you want to run from batteries, then you will have much more weight. 12 kV @ 10 mA is a potentially lethal. If it doesn't kill you it will hurt you in a way you will never forget. Don't work with LOPT, MOT, OBIT, NST and such while you are alone. RobG and nuetron 2 Quote Link to post Share on other sites
