摘要： A method for controlling a radio-frequency plasma generator including a supply circuit with a switch controlled by at least one control pulse train, for applying an intermediate voltage at a control frequency on an output to which is connected a resonator for generating a spark between two electrodes when a high voltage level is applied to the output. The method receives first and second measurement signals respectively representative of the operation of a combustion engine and of the type of spark generated; and real-time adjusts, based on the received measurement signals, at least one parameter selected from at least the intermediate voltage level, the control frequency, and the duration of the control train, to promote branching of the spark generated.

摘要： 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.
