发明名称 Control method and apparatus for a piezoelectric injector
摘要 The device (1) is for controlling an injector (3) having a transducer, adapted to be displaced, on receiving an electric command. It includes a cutting stage (7) having a switch (15) and units to aid the switching of this switch, and a selection stage (9) of the transducer. The cutting stage includes an inductance (14) in series with the switch, between the input of this cutting stage and a mass. The unit to aid the switching includes a condenser (32) in parallel with the switch.
