An aircraft electric power supply system (10) for supplying electric power to onboard electric devices (20) during flight. To reduce the devices' power draw, the electric power is supplied via modulation at an increment-percentage that is determined by present conditions. An optimum portfolio can be established for the electrical devices (20) collectively, this portfolio being selected in accordance with an energy-management criterion or other aircraft objectives.

1. A method of providing electric power to a plurality of electrical devices over a plurality of increments summing into a predetermined time period, said method comprising: determining, for each electrical device, a percentage of the plurality of increments that the electrical device must receive electric power for it to adequately perform in a present condition;establishing an optimum increment-pattern portfolio for the time period, the optimum pattern portfolio comprising an incremental distribution pattern for each electrical device that corresponds to its determined increment-percentage; andsupplying electric power via modulation to the plurality of electrical devices over the plurality of increments summing into the predetermined time period, wherein for each increment, each electric device is either supplied electric power or it is not supplied electric power;wherein said modulation-supplying step is performed in accordance with the established optimum increment-pattern portfolio. 2. A method as set forth in claim 1, wherein said optimum-pattern-portfolio establishing step establishes the optimum pattern portfolio so as to minimize the electric power collectively supplied to the plurality of electric devices at each increment. 3. A method as set forth in claim 2, wherein said optimum-pattern-portfolio step is performed so as to minimize the variation in the electric power collectively supplied to the plurality of electric devices between adjacent increments. 4. A method as set forth in claim 1, wherein said optimum-pattern-portfolio step is performed so as to minimize the variation in the electric power collectively supplied to the plurality of electric devices between adjacent increments. 5. A method as set forth in claim 1, wherein voltage is not directly reduced for supply to electric devices. 6. A method as set forth in claim 1, wherein the time period is at least 5 seconds. 7. A method as set forth in claim 6, wherein the increments are less than 1 second. 8. A method as set forth in claim 1, wherein each time period has at least ten increments. 9. A method as set forth in claim 1, wherein the plurality of electric devices comprises at least four electrical devices. 10. A method as set forth in claim 9, wherein the electrical devices comprise electrothermal ice protectors. 11. A method as set forth in claim 1, wherein the present condition comprises a sensed or measured condition, an input condition, and/or a programmed condition. 12. A method as set forth in claim 1, wherein the present condition comprises ice-formation information, an outside air temperature, now-being-supplied voltage, and/or resistances of the electrical devices. 13. An electric power system for performing the method of claim 1, said system comprising: a modulator that supplies electric power to the plurality of electrical devices in accordance with the optimum increment-pattern portfolio;an increment-percentage determiner that determines, for each electrical device, the percentage of the plurality of increments that the electrical device must receive electric power for it to adequately perform in the present condition; andan optimizer that establishes the optimum pattern portfolio for the time period. 14. A vehicle comprising a plurality of electrical devices adapted to operate when supplied with electric power, and the electrical power system set forth in claim 13. 15. A vehicle as set forth in claim 14, further comprising an onboard power source supplying electrical power to the plurality of electrical devices. 16. A vehicle as set forth in claim 15, further comprising an engine and wherein the onboard power source comprises an electrical generator rotated by the engine. 17. A vehicle as set forth in claim 14, wherein the vehicle is an aircraft. 18. An aircraft as set forth in claim 17, wherein the electrical devices comprise electrothermal ice-protection devices. 19. An aircraft as set forth in claim 18, wherein at least some of the ice-protection devices are located remote from each other.
