Abstract
본 발명은 전자비례밸브 구동제어회로에 관한 것으로서, 간단한 회로구성만으로 전자비례밸브의 구동상태를 제어할 수 있도록 하기 위하여, 전자비례밸브에 흐르는 전류량을 센싱하여 이 전류량에 대응하는 전압값을 검출하는 센싱저항; 센싱저항에 의해 검출된 전압값을 소정크기로 증폭하는 증폭기; 증폭기에 의해 증폭된 전압값과 외부에서 인가된 제어신호의 전압레벨을 비교하는 비교기; 및 비교기의 출력신호에 따라 전자비례밸브의 구동상태를 제어하도록 소정전류값을 출력하는 구동부로 구성하였다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electromagnetic proportional valve driving control circuit. In order to control a driving state of an electromagnetic proportional valve with a simple circuit configuration, a current value flowing through the electromagnetic proportional valve is sensed to detect a voltage value corresponding to the electrical proportional valve. Sensing resistance; An amplifier for amplifying the voltage value detected by the sensing resistor to a predetermined size; A comparator for comparing the voltage value amplified by the amplifier with the voltage level of the control signal applied from the outside; And a driving unit for outputting a predetermined current value to control the driving state of the electromagnetic proportional valve according to the output signal of the comparator.
