Abstract

See full text

An electronic circuit (101) for controlling a spark of a spark plug (SP1) in a capacitor discharge ignition system (100) for a combustion engine. The electronic circuit (101) comprises an ignition coil (110) dimensioned and configured to provide current to the spark plug (SP1), an ignition capacitor (C1) dimensioned and configured to supply energy to the primary winding (L1), an voltage source (130) dimensioned and configured to supply energy to at least one of the ignition capacitor (C1) and the primary winding (L1), a first switch (SW1) connected to the first primary terminal (TL1) and the first source terminal (TS1), a second switch (SW2) connected to the second capacitor terminal (TC2) and the second source terminal (TS2), and a third switch (SW3) connected to the second capacitor terminal (TC2) and the first source terminal (TS1). A capacitor discharge ignition system (100) including the electronic circuit (101) and a combustion engine including the capacitor discharge ignition system (100).
