Circuit and method for allocating power among generators

摘要

A circuit and method for allocating power among two or more generators to a single load on a shared bus includes a sharing regulator and a feedback loop for each generator. A digital share command input and current in the feedback loops will cause the sharing regulators to alter the power of the generators at the generator outputs, thereby allocating the load on the shared bus according to the share command, and confirming the allocation of power at the outputs.

1. A circuit for allocating power among at least two generators to a single load on a shared DC bus, the circuit comprising:
a first generator and a second generator electrically parallel to each other; a first sharing regulator serially connected to the first generator and a second sharing regulator serially connected to the second generator; a first filter serially connected between a first generator output and the DC bus and a second filter serially connected between a second generator output and the DC bus; a digital input to each of the first and second sharing regulators including a share command, wherein the share command provides a desired unequal power ratio to be supplied by the first and second generators; a first current feedback loop between an output of the first filter and an input of the first sharing regulator; and a second current feedback loop between an output of the second filter and an input of the second sharing regulator; wherein the share command at the digital input and current in the first and second current feedback loops will cause the first and second sharing regulators to independently alter the power of the first generator at the first generator output and the second generator at the second generator output, thereby allocating the load on the DC bus according to the power ratio of the share command.
