Beschreibung
Zusammenfassung:	The invention relates to an asymmetrical electric braking architecture for aircraft, comprising a certain number of electro-mechanical brake actuators (EBAs) for selectively applying a braking force on friction elements in order to slow down rotation of braked wheels, said architecture comprising: a brake control unit (BCU) for acting in normal mode to generate braking setpoint values in response to a braking order; electro-mechanical actuator controllers (EMACs), each including at least one inverter for supplying power to the EBAs in response to the braking setpoint values; at least one emergency brake power and control unit (EBPCU) including at least one inverter for supplying power to some of the EBAs in response to a braking order; and protection means for channeling power supplied by the EMACs or the EBPCU towards the actuators while preventing power from being diverted towards the architecture.
