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

In exemplary embodiments of the present system and method, the four HC-PSs 325 are electrically connected via suitable conducting paths (wires or electrically conducting tracks) 340 according to the exemplary connection topology shown in FIG. 3A. Person's skilled in the relevant arts will recognize that these exemplary paths/connections 340 are suitable for establishing the four HP-CSes 325 together to function as an H-Bridge, similar to the fixed H-bridges 210 of FIG. 2 above. However, the present system and method introduces additional power connection points or nodes N (N3, N4, N6, N16, N14, N13), along with current routing switches 350 and inductors 355; associated with these latter elements are modified or additional circuit paths 340. Together, these elements may be used to dynamically modify the operations of the power switch module 300 in ways that are not possible with a conventional, fixed H-bridge 210. The details of this are discussed further immediately below.
