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 alternative embodiments, the CF contactors 350 may be solid state (semiconductor) elements such as bi-polar junction transistors (BJTs) or MOSFETs. In some such embodiments, an exemplary A-PS may be implemented as an integrated circuit (IC).

Above, exemplary embodiments of the present system have been presented with exemplary components of various power, current, and/or voltage ratings, for example 1.7 kV switches and 10 kV switches. Other power/current/voltage ratings may be employed within the scope of the appended claims.

Power Stages and A-PEBB LRUs: In exemplary embodiments presented above in this document, an exemplary A-PEBB LRU 200.A includes two adaptable power stages A-PS 300, each of which may be substantially similar in internal design. Persons skilled in the relevant arts will appreciate that in alternative embodiments of the present system and method, an A-PEBB LRU 200.A may include only one, only two, or three or more adaptable power stages A-PS 300. Similarly, in alternative embodiments of the present system and method, an A-PEBB LRU 200.A may include one, two, or three or more adaptable power stages A-PS 300, some of which or each of which may differ in some respects from the exemplary A-PS 300 discussed above in this document.
