Re: [TCML] auto coil HV supply



Hi Ed; Thank you for your reply and thanks also to Dave and Miles for your replies. What I have is a dual ignition coil, dimmer switch and 24uf/370v motor run Cap setup and this thing is really "HOT'! I didn't realize how "HOT' until I powered a 12 inch lightning screen with a 5 inch center plate on it. I had used the HV supply with a Jacobs ladder and other stuff with no problems. When I powered the lightning screen with it, which is really just a lop-sided Capacitor, it really back fired! took out a fluorescent ballast on the same circuit and fried the mains outlet it was plugged into! Luckily the mains outlet was remote from the wall outlet, like an outlet box with a cord which was plugged to the wall. I tried to find something on [Corcoms] as some suggested but could nothing. What I was hoping was that someone could supply me with a diagram with component values, that I could build, on the order of the terry filter.
Thank you all; Doug

What kind of coil driver circuit are you thinking of?  Some will glitch
the line and some won't.  With the capacitor discharge light
dimmer/thyristor approach a normal EMI line filter can raise the
impedance at the coil end so much that the peak current is limited and
sparks are cut way down.

Hello; Can any one advise me on some kind of filter or device I can build or buy that will stop any HV spikes from an automobile ignition coil high voltage supply from backing into the mains?
