Abstract: Speed solenoid valve compared with the ordinary solenoid valve has a fast switching speed, switching time is generally less than 10 ms, it is closely related to its drive circuit. In order to reduce the switching time, a new type of drive circuit was designed based on integrated circuits and discrete components, according to highspeed switch valve drive demand. The circuit can be independently set the peak current, holding current and peak current control parameters etc.. Simulation and test resutls show that the circuit has good dynamic performance, and it has a reference value to improve the dynamic performance of highspeed switch valve.
Key words: highspeed switch valve; drive circuit; simulation and experiment
