摘要

A power conversion system for mobile power generation and support is configured to be adaptable to different, time-varying mission requirements, system statuses, environmental contexts, and for different power sources and power loads. Adaptability includes real-time, on-the-fly adaptation from DC-to-AC, AC-to-DC, AC-to-AC, and DC-to-DC conversion; adaptations from buck conversion to boost conversation; and from current source conversion mode to voltage source conversion mode. In an embodiment, individual internal power stages for one or more power electronics building blocks are equipped with multiple internal current routing switches/contactors. Current flow may be dynamically re-routed along different current paths associated with an H-bridge of each power stage. Alternative current routings allow for the introduction or removal of inductors at critical points along the current path. Such on-the-fly current rerouting, at the power transistor level, enables the adaptability of the power converter. Specific open/closed switch settings and specific current routing configurations are presented.

In turn, adaptable, large-scale electrical power systems 100 may employ adaptable power electronics converters 500.A, as shown with the exemplary system 100 of FIG. 1. In turn, and as will be apparent both from FIG. 1 and from FIG. 5, adaptable power electronics converters may be built from one or more adaptable line replacement units A-PEBB LRUs 200 which are field adaptable.

The operations of some non-configurable PEBB LRUs 200.nc are known in the art, and a description of their components, architecture, topologies, and operations will not be presented in detail in this document. It is noted that the General Electric Company has developed such Power Systems PEBB LRUs 200.nc in the past and expects to continue such development in the future; see for example [enter here patent numbers of recently filed applications].

FIG. 2 illustrates an exemplary A-PEBB line replacement unit (A-PEBB LRU) 200.A according to the present system and method. Exemplary A-PEBB LRU 200.A includes four power stages 210, 300 which are electrically coupled in series.
