Claim:
1. A method for managing a plurality of direct-current (DC) boost converters, the plurality of DC boost converters being output parallel-connected to a bus having a bus voltage, each of the plurality of DC boost converters receiving power input from a corresponding source, the power input having an input voltage and an input current, each of the plurality of DC boost converters having a controller communicatively networked to all other controllers of all others of the plurality of DC boost converters, the method comprising: each controller of a plurality of DC boost converters measuring an input voltage and an input current from its corresponding source; each controller of the plurality of DC boost converters communicatively sharing with all other controllers of all others of the plurality of DC boost converters quantities relating to: each controller of the plurality of DC boost converters determining a pulse-width modulation duty cycle for its DC boost converter via an adaptive cascade PI control architecture, wherein the adaptive cascade PI control architecture includes an input power apportionment PI gain stage, further wherein the adaptive cascade PI control architecture includes input parameters of the measured input voltage and the measured input current of its corresponding source, an actual bus voltage, and a desired bus voltage; and each DC boost converter operating in accordance with the pulse-width modulation duty cycle determined by its controller.
