ABSTRACT:
In a voltage boost circuit for driving a fuel injector of an internal combustion engine, a high voltage developed in the voltage boost coil will be discharged into the battery power supply through the boost coil by electrically energizing a discharge switching element provided in parallel to the charging diode. If the overboost compensation overlaps a boost execution period, the end of the boost execution period will await starting of the overboost compensation.
