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

Processor/Control: In various exemplary embodiments, A-PEBB LRU 200.A may include the use of or integration of a controller or microcontroller unit (MCU) 227 for regulation of switches, contacts, capacitors, cooling systems (not shown in FIG. 2), on-board status sensors (not shown in FIG. 2), and other factors requiring real-time control. Such control systems 227 may entail the use of microprocessors, digital input/output elements, memory (such a random access memory (RAM) and various forms of non-volatile memory), display systems, audio input and/or audio signalling systems, and/or analogue control elements known in the art or to be developed. The MCU 227 may employ suitable-coded software, stored in memory, to control various aspects of A-PEBB LRU 200. In particular, the MCU 227 may support the dynamic field configuration of A-PEBB LRU 200.A.

If will be noted in FIG. 2 that the MCU 227 is shown as being communicatively coupled with the active power stages 300.1, 300.2, but not with the isolation power stages 210.1, 210.2. This is exemplary only and is not limiting. While the present disclosure is directed towards the control of the adaptable power stages 300, in some embodiments of the present system and method the isolation power stages 210 may still have some internal elements requiring control or change. In the latter embodiments, the MCU 227 may be communicatively coupled with the active power stages 300 and also the isolation power stages 210.
