ELECTROMAGNETIC LOAD CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic load control device capable of securing the operation of a load stably even in the case where energy is used with a high frequency. SOLUTION: A solenoid 101a of an injector 101 is connected with a battery while a capacitor C10 to accumulate a higher voltage than the battery voltage is connected. An IC for driving 120 supplies the energy of the battery to the solenoid 101a for a period in which the solenoid 101a is operated by controlling of transistors T10 and T11 and the energy for quickening the response in the operation of the solenoid 101a is supplied to the solenoid 101a in the timing in accordance with the voltage Vc of the capacitor C10 by delaying the energy supply start timing of the capacitor C10 for the timing of starting the operation of the solenoid 101a by a larger degree with a higher voltage Vc of the capacitor C10 through controlling of a transistor T12.
