The invention discloses a piezoelectric control circuit (11, 51, 81) having an input (12), at which a temporally variable voltage signal (UE) is provided, and an interface (13, 53, 83) for connecting at least one voltage-controlled piezoelectric actuator (Pz). A sync monitoring circuit (SK) detects the phase angle of the voltage signal and controls a converter circuit (16, 56, 86), in particular a switching matrix which is connected between the input and the interface, on the basis of the phase angle of the voltage signal in such a manner that the interface outputs a control voltage (Us) with a predetermined time curve, in particular pulses composed of sections of an AC voltage. A method for controlling a piezoelectric actuator arrangement, a piezoelectric actuator device having the piezoelectric control circuit according to the invention and a metering valve with the latter are also described. |
