Vorrichtung und Verfahren zum Ansteuern wenigstens eines kapazitiven Stellgliedes

摘要

The invention relates to a device for controlling at least one capacitive actuator (P1 to Pn) by means of a control circuit (ST) which has a series connection comprising a charging capacitor (C1), a discharging capacitor (C2), an electric coil (L) and at least one actuator with associated selector switch (T1-Tn). The control circuit (ST) also has a discharge switch (Te) whose drain terminal is connected to the interconnection point between the two capacitors (C1 and C2), and whose source terminal is connected to the drain terminals of the selector switches (T1 to Tn) via decoupling diodes (D1 to Dn).
