摘要： 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.

摘要： Disclosed is an electromagnetic valve driving circuit capable of reducing a load of a booster circuit. 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.
