Abstract
An apparatus for delivering AC power to an AC load may include a plurality of inverters to receive direct current (DC) power from a respective DC power source and respectively provide AC power to an AC load. The apparatus may further include a first controller to generate a first control signal based on total AC current and total AC voltage being delivered to the AC load by the plurality of inverters. The apparatus may further include a plurality of secondary controllers to each receive the first control signal and each produce a respective secondary control signal based on the first control signal. The respective secondary control signal for each of the plurality of secondary controllers is configured to control a corresponding one of the plurality of inverters to provide a portion of the AC power.
