Abstract
Disclosed is a system for interdependent control of multiple power sources. The system includes at least first and second power sources for supplying power to an electrical load. At least first and second sensors are respectively coupled with outputs of the first and second power sources, such that the first and second sensors respectively emit first and second signals indicative of the output of the first and second power sources. A comparator unit is coupled to the first and second sensors for comparing the first and second signals emitted by the first and second sensors. The comparator unit is configured for emitting a difference signal indicating a difference between the first and second signals. A controller unit coupled to the comparator unit and at least one of said first and second power sources is configured for controlling at least one of said first and second power sources based on the difference signal.
