ABSTRACT:
In one embodiment, a capacitive discharge ignition system has a charge coil and an ignition coil including primary and secondary windings wound on a common stator structure. The charge coil is coupled to the primary winding of the ignition coil by an SCR and a main capacitor such that the capacitor is first charged by the charge coil and then discharged through the SCR into the primary winding of the ignition coil when the SCR fires. During discharge of the capacitor, the charge coil also supplies current to the primary winding of the ignition coil. The SCR may be fired by a triggering circuit which includes a capacitor network connecting the gate of the SCR to the charge winding and main capacitor or through a breakdown effect of the SCR absent the provision of a triggering circuit. The circuit arrangement obviates the need for the usual charging diode between the charging coil and the main capacitor. Several embodiments of triggering circuit for the SCR are disclosed.
