Abstract
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.
