Original poster: "Herwig Roscher" <herwig.roscher@xxxxxx> Hi, I am thinking of building a small DC resonant charging TC. As there are no 15 kV NSTs available in this country, I need to look for another source of HV. How many mA of filtered DC could I expect to get from a standard 12 V car ignition coil? Target DC voltage is 15 kV.
Most auto coils are 100:1 turns ratio... I've got some impedance data at http://home.earthlink.net/~jimlux/hv/igncoil.htm The DC resistance of the secondary is pretty high....
Any help is appreciated very much. Bye Herwig ---------------------------------------- Greed is the root of all evil ! ----------------------------------------
