The secondary circuit includes a spark gap. The primary circuit includes a capacitor that can be discharged. The voltage discharged by the capacitor is coupled by the transformer to the secondary circuit where it produces an ignition spark across the spark gap. The primary circuit is a resonant circuit that is repeatedly excited keeping the ignition spark burning as an arc. Current or voltage in the secondary circuit are detected to control the energy introduced into the spark gap. | |
