본 발명은 클러치 전류 제어 회로 및 이를 구비한 전자제어밸브에 관한 것으로, 본 발명의 실시예에 따른 클러치 전류 제어 회로 및 이를 구비한 전자제어밸브는, 압축기와 연결되는 클러치의 전류를 제어하는 회로로서, ECV(Electric Control Valve) 샤프트의 이동량에 따라 저항값이 가변되는 스트레인게이지(straingauge); 상기 스트레인게이지의 저항값 변화에 따라 결정된 게이트-소스 전압과, 임계 전압의 비교를 통해 스위칭 동작을 수행하되, 제1 스위칭 동작 상태에 의해 제1 클러치 전류의 흐름이 발생하는 스위칭소자; 및 상기 스위칭소자와 병렬로 연결하되, 상기 스위칭소자의 제2 스위칭 동작 상태에 의해 제2 클러치 전류의 흐름이 발생하는 저항;을 포함한다.

    A clutch current control circuit may include as a circuit for controlling a current of a clutch connected to a compressor, a strain gauge, wherein a resistance value of the strain gauge is varied according to the movement amount of an Electric Control Valve (ECV) shaft; a switching element of performing a switching operation by comparing a gate-source voltage determined according to a change in the resistance value of the strain gauge and the threshold voltage, and allowing a flow of a first clutch current to generate by a first switching operation state; and a resistor connected in parallel with the switching element, and allowing a flow of a second clutch current to generate by a second switching operation state of the switching element.
