A power supply voltage booster avoids inadequate step-up capability. In a voltage boosting circuit, a switching device connects and disconnects between the ground potential and one end of the coil, the other end of which is supplied with a supply voltage VB. The switching device is repeatedly turned ON and OFF such that the capacitor is electrically charged from the force in the coil when the switching device is turned off. A charging control circuit turns off the switching device when current flowing through the switching device into the coil is determined to have increased to a switch-off threshold value when the switching device is ON, and turns on the switching device upon determining that the charging current flowing to the capacitor from the coil decreases to a switch-on threshold value when the switching device is OFF. The charging control circuit sets the switch-off threshold value to a larger value as the supply voltage VB is lower. Thus, inadequacy of the step-up capability caused by a drop in the supply voltage VB can be avoided.

In an electromagnetic injector control apparatus for an engine, a capacitor is connected to a power supply and a solenoid of an injector for accumulating electric charge at a voltage higher than that of the power supply. A driving circuit controls transistors to supply energy from the power supply to the solenoid during an operation period of the solenoid. The driving circuit also controls a transistor so that a timing to start supplying the accumulated energy from the capacitor to the solenoid is delayed from a timing to start the operation of the solenoid as the voltage of the capacitor increases. Thus, the accumulated energy is used to speed up the operating response of the solenoid. The supply of the accumulated energy to the solenoid is stopped when a current flowing in the solenoid reaches a predetermined cut-off level. The capacitor is set to retain an offset of at least a predetermined quantity to be left therein when energy of a counter-electromotive force of the solenoid is recovered at the end of operation of the solenoid.
