ABSTRACT:
A device to control the charging rate of an ignition coil for an internal combustion spark ignition engine. The device controls the turn-on rate of the primary coil by slew-rate limiting using switching devices and a Miller-effect capacitor in order to reduce secondary oscillation magnitudes originated by a sharp transition of the controlling switch.
