    • The present invention realizes an injector drive circuit capable of providing high output power of a boost convertor while suppressing increases in size and cost thereof. An injector energizing circuit 200 includes an FET 2 which applies a high voltage 100a generated by a boost convertor 100 to an injection valve 20. The boost convertor 100 includes an input side capacitor 103, a boosting FET 105, a boost coil 104, a boost diode 106, and FETs 108 and 109 provided in association with a negative pole of an output side capacitor 107. During a period in which the high voltage 100a is applied to the injection valve 20, a gate signal 108a of the FET 108 is turned ON and a gate signal 109a of the FET 109 is turned OFF. Consequently, the boosting FET 105 performs a switching operation to turn OFF the gate signal 108a of the FET 108 and turn ON the gate signal 109a of the FET 109 during a period for charging into the output side capacitor 107. Thus, energy required for boosting can be reduced and an improvement in output is enabled.

    • An internal combustion engine controller comprises a booster coil connected to a battery and a booster capacitor. A switch element is connected to the booster coil to control the passage of current through the booster coil and an interruption of the current. The booster capacitor accumulates electrical energy generated with an inductance of the booster coil at the time of the interruption of the passage of the current. A booster control circuit carries out control in a constant boost switching cycle so as to pass the current through the booster coil and the switch element until the current reaches a preset switching stop threshold value and then interrupt the current to charge the energy generated with the inductance of the booster coil into the booster capacitor. The booster control circuit is configured to ensure a minimum time period for the booster capacitor-charging of the energy within the boost switching cycle.

    • Disclosed herein is a fuel injection control apparatus for an internal combustion engine, capable of opening and closing accurately a valve of the fuel injector even when the quantity of injection required is small and a pulse duration of a driving pulse signal to the fuel injector is short.A fuel injector pulse width computing unit 9a calculates, from the operational state of the internal combustion engine and the fuel pressure detected by a fuel pressure sensor, pulse width of a pulse signal which drives the valve of the fuel injector. After an valve-opening command has turned on and a high valve-opening current for opening the fuel injector valve has been supplied from a high-voltage source to the fuel injector, a fuel injector driving signal waveform command unit 9b discharges the current and supplies from a low-voltage source a small hold current Ih2 that allows the fuel injector to maintain the valve-open state. Also, during the time from supply of the valve-opening current to an arrival at the value of the hold current Ih2, after the elapse of a previously assigned rapid-discharge starting time Tsy from the turn-on of the valve-opening command, the fuel injector driving signal waveform command unit 9b rapidly discharges the current until the hold current Ih2 has been reached.
