ABSTRACT:
A solid state ignition system operating from a relatively low potential direct current input source for use with an internal combustion engine in which a combustible gaseous mixture is detonated by means of the introduction therein of a spark produced by a relatively high potential, high frequency, constant current pulse generator in response to ignition timing signals associated with the engine, the generator including a relatively high frequency pulse energy oscillator triggered by the ignition timing signals and providing such pulse energy to a circuit producing constant current pulses of such energy over a relatively wide input potential operating range, the high frequency continuous wave pulse energy then being power amplified to operate a solid state switch opening and closing the primary circuit of transformer circuitry coupled to the engine's spark plugs.
