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 control device for an ultrasonic piezoelectric actuator including a first stage supplied by a DC voltage source and including a mechanism forming a second DC voltage above that voltage delivered by the DC voltage source, and a second stage including a mechanism amplifying the second voltage and chopping the voltage obtained by excitation of the actuator with the chopped voltage, under control of a computer. The amplifying mechanism includes an inductor in electrical resonance with the piezoelectric actuator. The inductor is connected to the first stage so as to constitute, during formation of the second voltage, a secondary winding of a transformer forming part of a flyback voltage converter introduced into the first stage to develop the second voltage. The control device may find application to control of a fuel injector in an internal combustion engine.
