Abstract
An internal combustion engine ignition system includes: a primary coil provided with a center tap; a third switching element that interrupts and conducts a primary current flowing from a voltage application unit to the center tap; a first switching element connected to one end on a first winding side; a second switching element connected to the other end on a second winding side; an ignition control circuit that controls operation of each of the above switching elements, thereby performing discharge generation control that allows an ignition plug to generate a spark discharge, and thereby interrupting and conducting the primary current flowing to the second winding to perform discharge maintenance control that maintains the spark discharge generated in the ignition plug; and a current circulation path that circulates a current flowing from the second winding to the second switching element.
