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

Persons skilled in the relevant arts will appreciate that the specific functionality and control functions of the software may be implemented via one or multiple processors of MCUs 227, 327, 527, and may further be partly implemented via other digital or analog processing units (not illustrated in the figures) which may be associated with transport vehicles that employ the present power electronics systems 100. Thus, the methods disclosed herein may be implemented via a single MCU 227, 327, 527, or via software distributed among multiple networked MCUs 227, 327, 527. For example, in some embodiments of the present system and method, some environmental sensing functions and determinations, mission assessments, and electrical system status assessments (including assessments of power resources 110) may be performed by sensors and/or processing units (along with suitable memory and sensors) which are not part of the adaptable power converter 500; these functions may instead be performed by processors, memory, and sensors which integrated into elements of the larger mobile, adaptable electrical system 100. Such processors and sensors may include sensors/processors associated with various power resources (sources and loads) 110.

FIG. 7 presented a flow chart of an exemplary method 700 for automated regulation and adaptability for a power converter 100 according to the present system and method.
