Abstract

An ignition system includes an alternating current power source which feeds a transformer having a primary winding, the primary winding being coupled to an electronic switch. The electronic switch intermittently interrupts current flowing in the primary winding and in the output circuit of the power source. Such electronic switch is made operable by virtue of the peak excursions of the alternating current thus supplying the necessary collector or emitter potential, depending upon the manner in which the electronic switch is connected, for the entire igniter firing cycle. A capacitor in series with the output circuit of the power source and with the primary winding enables current to be transferred out of the power source to such primary winding. Such electronic switch also provides discrete separation between successive output waveforms of successive ignition firing cycles. The system employs a temporary change accumulator inductor in the output circuit in series with the primary winding. Such charge accumulator inductor is an alternative fix for the deficiencies in the output transformer core of the alternating current power source conventionally used by transformer manufacturers for such power souces, so that when an appropriate magnetic core is utilized the output winding of the output transformer will provide sufficient temporary charge storage to obviate the need of such charge accumulator inductor.
