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

In particular: It will be understood by persons skilled in the relevant arts that, in some embodiments of the present system and method, the power stages A-PS 300, A-PEBB LRUs 200.A, and power converters 500 are structurally composed of individual, fundamental electronic components such as power transistors 330, diodes 335, inductors 355, electrically conducting circuit paths 340 (typically composed of various metals or metal alloys), current flow switches/contactors 350, and other components such as resistors or capacitors which may not be shown in the figures. It will be further understood that for such embodiments, a complete description of the circuit topology and operations may be provided for entirely in terms of the connections and operations of the fundamental electronic components 330, 335, 340, 350, 355. The groupings of these components into functional/block/modular units such as RH-BC modules 320, HC-PSs 325, and CFC modules 375, as well as into adaptable power stages A-PS 300 and A-PEBB LRUs 200.A is for convenience of exposition.
