Abstract
Schaltungsanordnung zur Ansteuerung einer Zündspule, die folgende Merkmale aufweist:
- einen ersten Halbleiterschalter (T1) mit einer Laststrecke (D-S), die in Reihe zu einer Primärwicklung (L1) der Zündspule geschaltet ist, und mit einer Steuerelektrode (G) für die Ansteuerung nach Maßgabe eines ersten Ansteuersignals (A1);
- einen zweiten Halbleiterschalter (T2) mit einer Laststrecke (D-S), die parallel zu der Primärwicklung (L1) geschaltet ist, und mit einer Steuerelektrode (G) für die Ansteuerung nach Maßgabe eines zweiten Ansteuersignals (A2).
- a first semiconductor switch (T1) with a load path (DS), which is connected in series with a primary winding (L1) of the ignition coil, and with a control electrode (G) for the control in accordance with a first control signal (A1);
- a second semiconductor switch (T2) with a load path (DS), which is connected in parallel to the primary winding (L1), and with a control electrode (G) for the control in accordance with a second control signal (A2).
