Abstract

A method is provided for controlling an ignition system which includes a spark plug control unit adapted to control at least one coil stage, the at least one coil stage adapted to successively energize and de-energize to provide a current to a spark plug, each coil stage includes a primary winding inductively coupled to a secondary winding. The method includes measuring low side voltages at one or more of each coil stage and controlling a duty cycle or a pulse width of a PWM-signal of a step-down converter stage dependent on a battery voltage, a maximum primary current threshold, and the measured voltages.
