    摘要: A device for controlling a first control gate transistor, including: a second transistor and a third transistor series-connected between a first and a second terminals of application of a power supply voltage, the junction point of these transistors being connected to the gate of the first transistor; a terminal of application of a digital control signal; a circuit for generating an analog signal according to variations of the power supply voltage; and for each of the second and third transistors, a circuit of selection of a control signal of the first transistor representative of said digital signal or of said analog signal.

    摘要: An electrostatic converter includes: a stator provided with at least one electrode; a rotor including at least one blade provided with a counter-electrode, the blade being movable in rotation around an axis of rotation designed to coincide with a direction of an air flow; the electrode or the counter-electrode being coated with a dielectric material able to be biased, the stator and rotor being configured to allow a first relative movement between the electrode and counter-electrode around the axis of rotation of the rotary shaft of the rotor so as to generate an electrostatic torque when the rotor performs a rotation. The stator and the rotor are configured to allow a second relative movement between the electrode and counter-electrode so as to modify the electrostatic torque generated.
