Abstract
An electromechanical braking system is provided that includes an electromechanical brake actuator for converting an electrical drive signal into mechanical energy to effect braking on a wheel of a vehicle. The electromechanical brake actuator is operative based at least in part on a DC supply voltage typically provided by a main supply source. The system further includes an electrical energy back-up system which capacitively stores electrical energy and provides the stored electrical energy as the DC supply voltage in an absence of the main supply source.

11. A method of providing braking in an electromechanical braking system having at least one electromechanical brake actuator for converting an electrical drive signal into mechanical energy to effect braking on a wheel of an aircraft, the at least one electromechanical brake actuator being operative based at least in part on a DC supply voltage typically provided by a main supply source, the method comprising the steps of:
-
capacitively storing electrical energy;
providing the stored electrical energy as the DC supply voltage in an absence of the main supply source; and
using the provided electrical energy that was capacitively stored to generate the electrical drive signal for use in a commanded braking operation of the aircraft.
