Title: METHOD AND SYSTEM FOR SUPPLYING AN ELECTRICAL LOAD IN AN AIRCRAFT
Abstract:
A method for supplying electrical power to an electrical load (2) in an aircraft, said method comprising: - supplying of electrical power to the electrical load (2) by a main electrical power generating source (1); - measuring an instantaneous parameter characterising the main source (1); - determining a usage level of the main source (1) on the basis of the measured instantaneous parameter; - adjusting the voltage of the main source (1) as a function of the usage level; - measuring a voltage output from the main source (1); - comparing the voltage or the usage level with a predetermined threshold value; and - supplying of electrical power to the electrical load (2) by an auxiliary source (3) for storing electrical power when the measured voltage is less than the predetermined threshold value, so as to supply additional electrical power to the electrical load (2).
