Abstract:
A multi-charge ignition system includes a spark plug control unit adapted to control at least two coil stages so as to successively energise and de-energise the coil stages to provide a current to a spark plug. The two stages include a first transformer including a first primary winding inductively coupled to a first secondary winding; a second transformer including a second primary winding inductively coupled to a second secondary winding. An auxiliary primary winding is connected from the common high side of the primary winding in series to an auxiliary secondary winding, the other end of said auxiliary secondary winding is electrically connected to ground/low side, and includes a switch which selectively allows current to pass through the auxiliary windings.
