Abstract
An inductive-capacitive cyclic charge-discharge ignition system includes an ignition transformer primary winding in parallel with a capacitor and fed by an alternating current source providing a plural number of repetition cycles during each igniter firing period. Such repetition cycles cause the capacitor and primary winding to charge and discharge during each of the repetition cycles creating a plurality of ringing periods for each igniter firing period. A diode or an additional capacitor, or both, inserted in series with the parallel combination of the first stated capacitor and primary winding, substantially increases the velocity of arc provided by an igniter. Such arc has several components composed of luninous particles extending across the entire base of the igniter.

An inductive-capacitive cyclic charge-discharge ignition system for providing a plurality of ignition periods, comprising the combination of:
- an ignition transformer having a primary winding;
- a capacitor connected to the primary winding and forming a parallel circuit with said primary winding;
- a first diode in series with said parallel circuit;
- AC generating means having an output winding in series with the first diode for powering said first diode and parallel circuit with AC energy during each said ignition period, said output winding, first diode and parallel circuit forming a switchless output network;
- and
- timing means coupled to said AC generating means for controlling DC bias current to said generating means so as to duty cycle said generating means.
A method for producing electrical ignition power during each ignition period of an ignition system, comprising in combination the steps of:
- (a) duty cycling an AC generator so as to produce AC energy during each said ignition period;
- (b) generating multi-spectral bands of frequencies by passing said AC energy by means of an output winding of said AC generator through a diode in series with a parallel combination of a capacitor and a primary winding of an ignition transformer;
- and
- (c) exciting an electrical igniter with said bands of frequencies for each said ignition period.
