Abstract: A device for controlling a resonant ultrasound piezoelectric stage, including: a first stage of increasing a DC voltage to an intermediate DC voltage, a second modulation stage including an inductor connected to the intermediate DC voltage and a first switching transistor for selectively controlling a phase of charging the inductor and a phase of transferring the energy stored in the inductor in response to a first stream of command pulses, to generate an excitation voltage of the piezoelectric stage. The second stage includes a second switching transistor connected in series between the drain of the first transistor and a terminal of the inductor, suitable for limiting energy stored in the inductor during the charging phase in response to a second stream of command pulses, so as to reduce an amplitude of the excitation voltage.

Abstract: A device for driving ultrasound piezoelectric actuators, on the basis of a DC voltage. The device includes an impedance matching branch mounted in parallel with the actuators and including a capacitor in series with a selection switch, which is closed and opened, at the same time as the selection switch of the actuator to be excited, so that the voltage across the terminals of the matching capacitor and the voltage across the terminals of the selected actuator are almost zero before the start and after the end of the injection. A method of controlling the matching switch makes it possible to benefit from the capacitive charge during the pulse train causing the injection, while circumventing abrupt discharges at the start of the train. Such a device and method may find application to the engines of motor vehicles, as one example.
