In step 750, and based on the determinations of step 740, the method sets the appropriate open/closed states of contactors 350 throughout the power system. In step 750, the present system and method may also, concurrently send suitable power control commands to various power resources 110 through the electrical system 100.

Transformer: In some embodiments, variations may be employed in the power transformer 222 as well. For example, rather than employing a winding ratio of 1:1, some embodiments of the present system and method may employ other winding ratios such 1:2, 1:3, or 2:3. In an alternative embodiment, the A-PEBB LRU of the present system and method may be provisioned with two or more separate transformers, and further provisioned for field-selection of a particular transformer for routing the current. The field selection may be by way of additional switches, either mechanical, relayed-based, or transistor/IC-based, not shown in the figure. The latter embodiment may allow for field selection of transformers with different winding ratios, or among two or more

Adaptable power stage (A-PS) 300: In some embodiments of the present system and method, the A-PS 300 can be built from discrete elements (current flow switches 350, power switches 325, inductors 355) which are discrete elements, employing mechanical contacts (relays) as the current flow switches 350. All these discrete elements may be built into an A-PS 300 system on a single module as an integrated unit. The power transistors 330 of the power switches 325 may be IGBT transistors, MOSFET transistors, or other types of solid state power transistors.
