Re: ignition coil for high voltage source
I haven't been attending to this particular subject but it just now
caught my eye. Sounds like you pulse a xfmr directly from the power line
thru a triac or light-dimmer & a series capacitor. I can attest to the
fact that that works just fine: Some 10 years ago I designed and built
several neon-tube assemblies that employed just such a circuit. They
incorporated a 4 ft. tall neon tube standing upright in a sealed and
windowed metal case and the transformer was of a conventional but
high-ratio type, i.e., not magnetically-shunted.
The purpose of the device was to provide for a strobe-light effect within
the field of view of the camera that is used to make the photo-finish
images at racetracks. Such a camera is focussed on the finish line and
its field of view encompasses only the finish line & what's in front of
it and nothing else. In this instance, the finish line is, literally,
the neon tube--flashing on 120 x per second--and what's in front of it is
the horses as they pass by. That's a clever technique but I won't
discourse further on it as it's off-topic.
