摘要： According to one embodiment, there is provided an internal combustion engine ignition system, including: a spark coil having primary and secondary coils, the spark coil being configured to apply a high voltage to a spark plug from the secondary coil; a power transistor configured to perform an intermittent control on a current flowing through the primary current for a given time period, based on an inputted multipulse; a DC-DC converter electrically connected to the primary coil and configured to control a bias voltage applied to the primary coil; and a converter control circuit configured to control the DC-DC converter while switching a control mode to either a feedback mode in which the bias voltage is increased or decreased based on a detection value of the bias voltage, or a forced voltage increase mode in which the bias voltage is forcedly increased.
