发明名称 Method and circuit for driving at least one capacitive actuator
摘要 A capacitive actuator is charged from a charged energy storage capacitor via a transformer by applying pulse width-modulated control signals with a specific voltage, frequency and duty ratio to a charging switch disposed on the primary side. The duration, magnitude and waveform of the actuator voltage can in this case be chosen as required. The actuator can be discharged in the same way.
