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

Power Converters 500 and Electrical Systems 100: While FIG. 1 illustrates a single A-PEBB converter 500.A, persons skilled in the relevant arts will appreciate that a large-scale electrical system may employ multiple, interconnected A-PEBB converters 500.A (possibly along with one or more conventional PEBB converters), with some A-PEBB converters 500 being end-point power sources for various loads and other A-PEBB converters providing mid-power-stream voltage or current conversions. The details of such electrical system topologies are beyond the scope of this document.

“Buck” and “Boost”

In this document, the term “buck converter” refers to an electrical converter which accepts a higher input voltage B and reduces it, or steps it down, to a lower voltage A. “Bucking” as used herein refers to the act or process of stepping down the voltage from B to A.

In this document, the term “boost converter” refers to an electrical converter which accepts a lower input voltage A and increases it, or steps it up, to a higher voltage B. “Boosting” as used herein refers to the act or process of stepping up the voltage from A to B.

Exemplary Adaptable Electrical Power Systems

In exemplary embodiments, the present system and method is directed in part towards integrated and adaptable/flexible power-generation/power-distribution systems 100, which are adaptable to various power/energy sources 110.1 (prime movers/gensets, solar power, energy storage (batteries, etc.) and a variety of loads 110.2 (AC, DC, pulsating, continuous, and UPS etc.) within the overall system 100.
