Method and apparatus for power imbalance correction in a multi-phase power generator

摘要

A method and apparatus for power imbalance correction comprising: a plurality of converters for converting a plurality of DC inputs to a multi-phase AC output, and coupling the multi-phase AC output to a multi-phase AC line, and a controller coupled to the plurality of converters. The controller determining whether phases of the multi-phase AC output are balanced, and controlling when all phases of the multi-phase AC output are not balanced, at least one converter of the plurality of converters to balance the multi-phase AC output.

1. An apparatus for power imbalance correction comprising:
a plurality of converters for converting a plurality of DC inputs to a multi-phase AC output and coupling the multi-phase AC output to a multi-phase AC line, wherein the plurality of converters comprises a first converter and at least a second converter separate from the first converter, and wherein the first converter couples output power to a first subset of lines of the mufti-phase AC line and the at least a second converter couples output power to a second subset of lines of the multi-phase AC line, the second subset different from the first subset; and a controller coupled to the plurality of converters for:
(i) determining whether phases of the multi-phase AC output are balanced, and(ii) controlling, when all phases of the multi-phase AC output are not balanced, at least one converter of the plurality of converters to balance the multi-phase AC output.
