    • The invention relates to an ignition system for a 14 V or 42 V vehicle supply, which is directly applied to the ignition transformer by means of the semiconductor power end-stage, without intermediate network components. The semiconductor power stage is activated by an ignition controller, according to an input signal from a higher engine controller. A current thus grows on the primary side of the ignition transformer. The primary side of the ignition transformer is extinguished for a given period after a given maximum current value is first achieved. During this period, a high voltage for spark initiation is generated at the electrodes of the spark plug, by the principle of self-induction. After striking of the spark, the primary side of the ignition transformer is time-controlled and current-limited until the end of the ignition process, which is determined by the higher motor controller. The time control works with selected given time intervals, by means of which the semiconductor power stage is alternately switched on and off. A current limit is superimposed on said time control, which always extinguishes the primary side of the ignition transformer when the primary current reaches the given maximum value.

    • The invention relates to a rapid multiple spark ignition during which the maximum breakdown voltage for the spark breakdown is repeatedly available during an ignition point window. The ignition system operates with a direct-current converter, with which the vehicle electric system voltage is increased, and with rod ignition transformers whose minimized ignition coils permit a rapid recharging. The ignition electronics operate with a power-output stage that charges the rod ignition transformer by switching a power switch in the ground path of the primary winding. The output stage-power switch is controlled by a timer, which clocks the power switch for the charging of the rod ignition transformer and which, in order to achieve the spark breakdown after charging the ignition transformer, switches to ground in a long conductive manner the primary side of the ignition transformer for a predetermined period of time.
