Integrated electrical power extraction for aircraft engines

An aircraft power system comprising:

• an aircraft engine;
• a plurality of AC generators driven by the aircraft engine, wherein each AC generator is independently operational to supply AC power to a respective AC power bus in response to commands from an electrical power extraction (EPX) controller ;
• and
• at least one generator driven by the aircraft engine, wherein the at least one generator is operational to selectively supply additional AC power to each AC power bus in synchronization with each respective AC generator in response to commands from the EPX controller.

A method of providing aircraft power, the method comprising the steps of:

• driving a plurality of generators via an aircraft engine spool such that each generator provides AC power to a respective power electronic system;
• driving at least one generator via a different engine spool to selectively provide additional AC power to each power electronics system;
• and
• controlling the at least one generator to selectively supply additional AC power to each power electronics system in parallel with each respective AC generator.
