DEVICE FOR CONTROLLING AT LEAST ONE CAPACITIVE ACTUATOR

摘要

The invention relates to a device for controlling capacitive actuators for fuel injection valves for instance. The actuators comprise an energy source (V) and a charging capacitor (C1). A series connection of the primary coil (w1) pertaining to a transformer and a charging switch (S1) is arranged in parallel to the charging capacitor and in the device. A series connection respectively is arranged in parallel in relation to the series connection consisting of the secondary coil (w2) of the transformer and a decharging switch (S2), whereby said first series connection consists of an actuator (P1 to Pn) and a selector switch (A1 to An) allocated thereto. Diodes (D1, D2) are switched in parallel to the charging switch (S1) and the decharging switch (S2).
