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

Additional Elements: The terminal power stages 300.1, 300.2, also function as bridge converters, but are both field configurable as is discussed further below (see in particular FIG. 3 series and FIG. 4 series diagrams).

It will be understood that the topology of the exemplary A-PEBB LRU 200.A of FIG. 2 is exemplary only and not limiting. Other topologies may be employed within the scope of the appended claims. Similarly, certain essential components have been omitted from the figure for the sake of clarity. These components may include, for example and without limitation:

(i) An exterior casing or enclosure for the A-PEBB LRU 200.A;

(ii) Additional capacitors, as well as resistors and/or inductors; and

(iii) Connector components to electrically and physically link the A-PEBB LRU 200.A into a backplane.

Adaptable Power Stage (A-PS)

The exemplary A-PEBB LRU 200 of FIG. 2, discussed immediately above, consists of four bridge converters 210, 300, also referred to as power stages 210. The two “outer” bridges or power stages are self-configurable or adaptable power stages 300. FIG. 3A presents a schematic illustration of an exemplary adaptable power stage (A-PS) 300 according to the present system and method.
