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

FIG. 3C presents a Table Λ 390 which lists the above-defined conversion modes CM 392 for exemplary A-PS 300, along with the suitable open/closed settings 395 for the contactors 350 and the appropriate input/output polarity settings 397.

It will be noted that the buck & boost configuration (CM3) utilizes only a half of the full-bridge, with half of the rated H-bridge capacity, but provides for either buck or boost functionality at any given time. As further noted in Table Λ 390:

(I) For CM4 and CM5, the default and preferable setting for SW14 is open. However, SW14 could be in either open or closed position (non-conducting or conducting). In operation, and in some embodiments, SW14 may be left in its previous position (open or closed) even when other switches may be reset to change into modes CM4 or CM5.

(II) For CM5 to be operable in an A-HPEBB LRU 200, both adaptable PEBBs (A-PEBBS) 300.1, 300.2 (that is, the two terminal A-PEBBS, see FIG. 2) must each be set to mode CM5. The applicable input and output connections then are for the entire A-PEBB LRU—that is, connections (X0, Y0) and (X5, Y5) (see again FIG. 2).
