A boost driving FET (202) is connected to a route formed between the booster circuit (100) and a first terminal of an injector (3). A battery-side driving FET (212) and a battery protection diode Db are connected to a route formed between a positive-polarity side of a power supply and the first terminal of the injector (3). A freewheeling diode Df is connected at a first terminal thereof to a portion between the first terminal of the injector (3) and the battery protection diode Db, and at a second terminal thereof to a grounding side of the power supply. An injector downstream-side driving FET (220) is connected to a route formed between the second terminal of the injector (3) and the grounding side of the power supply. In addition to operating the FETs (202, 212, and 220) according to a level of a current which flows through the injector (3), a control circuit (240) activates the battery-side driving FET (212) during a period in which the boost driving FET (202) repeatedly turns on and off a plurality of times.

摘要： An injector energizing circuit (200) includes a first 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 second and third FETs (108,109) 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 second FET (108) is turned ON and a gate signal (109a) of the third FET (109) is turned OFF. Consequently, the boosting FET (105) performs a switching operation to turn OFF the gate signal (108a) of the second FET (108) and turn ON the gate signal (109a) of the third 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.
