DEVICE FOR CONTROLLING AN ELECTRONICALLY-MONITORED ULTRASONIC PIEZOELECTRIC ACTUATOR, AND METHOD FOR USING SAME |
摘要 |
The invention concerns a device for controlling an ultrasonic piezoelectric actuator, electronically monitored from a computer controlling a continuous current voltage source. The invention is characterized in that it comprises a DC to DC converter, powered by the voltage source, delivering at least in output a direct current voltage (Vs) between two end terminals (B1, B2) parallel to which is connected at least an arm, consisting of two alternately controllable series-connected bridge switches and whereof the midpoint is alternately connected to the two output terminals of the DC to DC converter by a load consisting of at least an actuator in series with a resonance inductor. |
