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.

說明書

The present system and method pertains to power converters 500 and structural building blocks (PEBBs) 200 of the power converters such as PEBB LRUs 200; the systems described herein are generally configured to operate with one or more power sources 110.1 at a source end and one or more loads 110.2. By convention, the sources are attached to what is referred to as a “first end” or “power end” of PEBBs 500, and the loads are connected to what is conventionally referred to as “second end” or a “l(fā)oad end” of the PEBBs 500. It is noted, however, that:

(i) Larger system topologies may entail multiple power connection points and/or load connection points, so that the “ends” should not be construed as necessarily referring to two structurally opposing ends of the physical system, and

(ii) in some exemplary embodiments, it is an element of the present system and method that the A-PEBB LRU's 200.A and PEBBs 500 may be adapted or reconfigured so that source connections become load connections, or vice-versa.

Adaptable PEBB (A-PEBB): In FIG. 1, the exemplary PEBB converter 500 is an adaptable PEBB 500.A (A-PEBB), which is discussed in further detail throughout this document. Though only one A-PEBB converter 500 is illustrated in FIG. 1, persons skilled in the relevant arts will appreciate that a single large-scale electrical system 100 may employ multiple PEBB converters 500 (some of which may be conventional PEBB converters, along with the A-PEBB converters 500.A which are the focus of the present system and method).
