  • Patent number: 9467077
    Abstract: A method and architecture processing electrical energy regenerated from an aircraft, to address drawbacks posed by customary solutions for dissipating low energy of resistors, conventionally ceramics, which require a significant volume of ceramic and an additional power converter. The method and architecture return energy to an electric generator to convert the energy into mechanical energy. The architecture includes a reversible electric generator, driven by a thermal machine and configured to deliver an AC voltage, electric actuators, and a voltage converter circuit with multiple links. The circuit includes AC voltage rectifiers for voltage originating from the generator and power converters arranged on the multiple links to drive as many electric actuators. The converter circuit also includes a mechanism for electrical energy inverse transmission applied to the generator operating in a motor mode.

  • Publication number: 20140008972
    Abstract: A generation method performed by a generator module of an electricity network of an aircraft, the electricity network including a power supply line powered by the generator module, a DC bus powered from the power supply line via a rectifier, and at least one electrical actuator powered with AC from the DC bus via an inverter. The generation method includes: delivering an AC voltage as a function of a voltage setpoint and of a voltage measured in the on-board network; and determining the voltage setpoint as a function of an operating parameter of the actuator.

  • Patent number: 8207780
    Abstract: An electronic control module for a field effect transistor includes a gate, a drain and a source. The electronic control module includes: a control circuit including: a power supply able to provide a fixed potential to the gate of the field effect transistor; and an amplifier stage able to vary the potential of the source of the field effect transistor with relation to the potential of the gate of the field effect transistor; and a field effect transistor whose gate is connected to the fixed potential; and source is connected to the amplifier stage.
