Claim Text:
1. A power electronics and control system for powering an AC load from multiple DC power sources each through a respective single conversion stage, the system comprising: a plurality of controllable DC-to-AC inverters each comprising a control signal input, a DC input, and an AC output; a plurality of DC power sources each comprising a DC electrical output operable to provide DC electrical power to the DC input of a respective one of the plurality of controllable DC-to-AC inverters; a plurality of DC sensors each operable to measure at least one characteristic of the DC electrical power output by a respective one of the plurality of DC power sources; an AC power bus coupling the AC outputs to each other to provide a combined AC electrical power to the AC load; an AC sensor operable to measure at least one characteristic of the combined AC electrical power provided by the AC power bus to the AC load; and a processor configured to generate a respective control signal for the control signal input of each of the controllable DC-to-AC inverters based on the measured at least one characteristic of the respective DC electrical power output by each of the DC power sources and the measured at least one characteristic of the combined AC electrical power.
