| 摘要 |
The invention is related to an electric circuit with one power amplifier (V1) for at least two piezoelectric actuators (C1, C2), said piezoelectric actuators (C1, C2) being in preferably antagonist arrangement connected mechanically in series and being connected electrically with each other and operated or clocked by a control circuit, such as a pulse modulator circuit, for time-variant energizing of the piezoelectric actuators (C1, C2) in push-pull fashion, said power amplifier (V1) being connected to a junction point between the two piezoelectric actuators (C1, C2), characterized in that said power amplifier (V1) is connected to a one directional diode (D1) and in that at least one buffer capacitor (C3) is provided downstream the one directional diode (D1) with regard to the power amplifier (V1). |
