Architecture of an aircraft braking system

The structure has a power module (7) for sending phase currents to electromechanical actuators (3) such that the actuators exert braking efforts. A control module (8) controls the power module in response to a braking command such that the appropriate phase currents are sent to the actuators to increase the desired braking efforts. A power supply box (20) comprises a high-voltage converter (21) generating high voltages for providing high power to the power module. The box comprises a low-voltage converter (22) generating low voltages for supplying low voltages to the control module.
