The object of the invention is to provide a driving circuit of a diesel engine position control type actuator. The driving circuit of the diesel engine position control type actuator includes a driving signal input circuit, an over-current protective circuit, a driving current feedback circuit, a pulse feedback circuit and an emergency stop signal input circuit. The driving circuit of the diesel engine position control type actuator has the advantages that (1) the output of a driving logic is realized by using a photoelectric coupler and MOSFET as main logic conversion elements, and the selection of element types is simple and easy to realize; (2) a system can adjust PWM control signals according to a feedback driving current and a driving pulse, thus the self-control of the system is realized; (3) the driving the circuit of the diesel engine position control type actuator has an over-current protection function, when a current is too large, the over-current protective circuit can turnoff a Q8 control switch at the lower end of the actuator to prevent the damage to the circuit caused by the excessive current; and (4) when the driving circuit fails, the actuator can be turned off independently in time through the emergency stop signal input circuit, and the driving the circuit of the diesel engine position control type actuator has a function of safety protection.
