Abstract
A power distributing mechanism includes a regulating circuit disposed between at least two circuit portions. The regulating circuit has bifilar-wound windings electrically coupled to the circuit portions. In a first embodiment, the two circuit portions withdraw power from two separate power sources. The regulating circuit, in response to power withdrawn from the power sources passing through the circuit portions, proportionally allocates the withdrawn power between the circuit portions. In a second embodiment, the two circuit portions withdraw power from a single power source. The two circuit portions serve as redundant reliability backup to each other. In the event of circuit failure in one of the circuit portions, the regulating circuit in response to the failure proportionally allocates power to the remaining functioning circuit portion.
