<p>An expandable hybrid electric generator (20) includes a number of power blocks (22) that may be nearly identical to one another. The power blocks (22) are controlled by a master controller (34), and an external supervisor (30) performs some master controller (34) functions should the master controller (34) fault. The power blocks (22) each include a battery bank (42) and an inverter/charger (44), both of which couple to a DC bus (40). The inverter (44) and an AC generator (50) couple to an AC bus (24). The DC busses (40) of the power blocks (22) remain independent of one another, but all power blocks (22) couple together at the AC bus (24). The master controller (34) issues instructions to the inverters (44) that maintain approximately equal states at the independent DC busses (40) of the power blocks (22).</p> |
