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

Terminal, Adaptable Power Stages: As may be seen from FIG. 2, in one exemplary embodiment the four power stages include two terminal-power stages 300.1 and 300.2, which are adaptable power stages; the internal operations of these two end-power stages are described further below (see especially FIGS. 3 and 4). In some exemplary embodiments of the present system and method, source power 273.1 from one or more power sources 110.1 may be received at one of the two terminal power stages 300 (at terminals X0, Y0), while output power 273.2 for loads 110.2 may come from the other of the two terminal stages 300, at terminals X5, Y5).

It is noted that, while in the figure, input power is provided for at power stage 300.1 and output power is output from power stage 300.2, this is for purposes of illustration only and is not limiting. In some embodiments, it is an advantage of the present system and method that adaptable power stages 300 can be reconfigured, in the field, to reverse the direction of voltage change and/or current flow (for direct current) through the A-PEBB LRU 200.A, so that for example DC electrical current can be input at terminals X5, Y5 with output current then yielded at terminals X0, Y0.
