A secondary power system for an aircraft utilizes a variable frequency electrical distribution system that provides power to one or more loads that can tolerate distortion components. In addition, a DC distribution system is coupled to the variable frequency distribution system and is isolated from a fixed frequency electrical distribution. Distortion caused by rectification for the DC system is isolated from the fixed frequency system, thereby improving the power quality in the fixed frequency system.


[ I claim:] [1.] A power system for an aircraft having an engine, comprising:a variable frequency generator coupled to the engine;a variable frequency electrical distribution system coupled to the variable frequency generator, wherein the variable frequency generator receives power from the variable frequency electrical distribution system during operation in a starting mode to start the engine and which delivers power to the variable frequency electrical distribution system for variable frequency loads during operation in a generating mode;a power conve...
