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 descriptions in this document of the system operations in terms of both fundamental components and alternatively in terms of functional/block/modular units are intended to supplement each other, and should not be construed as limiting. In some alternative embodiments, some functional modules 320, 325, 375, 300, 200.A, 500 may employ alternative components or additional fundamental components, with the invention still being operative in terms of the functional modules 320, 325, 375, 300, 200.A, 500 as described herein. Similarly, fundamental electronic components 330, 335, 340, 350, 355 may be understood as being grouped or organized, for purposes of functional or operational description, into modules other than those specifically described in this document.

It should be noted that the simulation, synthesis, and/or manufacture of the various embodiments of this invention can be accomplished, in part, through the use of a variety of materials, including metals, non-metals, resins, epoxies, semi-conductors, glass, polymers, ferrous materials, non-ferrous materials, conductors, insulators, and liquids, some known in the art and some yet to be developed.

Where computer code is required for the present system and method, such as for control systems 227 running on microprocessors, computer readable code can be disposed in any known computer usable medium including semiconductor, magnetic disk, optical disk (such as CD-ROM, DVD-ROM) and as a computer data signal embodied in a computer usable (e.g., readable) transmission medium (such as a carrier wave or any other medium including digital, optical, or analog-based medium). As such, the code can be transmitted over communication networks including the Internet and intranets.
