In order to develop drive circuit for high pressure common rail injector solenoid valve, analysis the model of drive circuit and study the relation between voltage and electromagnetic response of solenoid valve. The controllable BOOST circuit was designed to provide the high voltage helping to improve electromagnetic response, and high and low voltage time-sharing driving circuit was designed based on current feedback control. Drive current can be adjusted automatically according to the peak current and holding current, with better consistency of peak current. The result of driving experiment for certain injector shows that: the new drive circuit has fast response, with only 0.045ms rising time for drive current reaching the peak value 22A, and peak current has good consistency.
