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.

Such adaptable power systems 100 may be used, for one example, to support shipboard power applications for “no manning required ships (NOMARS)”. NOMARS power systems 100 for ships with diverse missions will require modularity and adaptability based on operational and health conditions of the ship, based on varying mission requirements, and also based on the situational environment the ship is in. Advanced power electronics as a key enabling technology will play a vital role in such flexible NOMARS power generation and distribution system.

It is noted that while, in exemplary embodiments, the present system and method may be described herein in the context of NOMARS systems, the present system is equally applicable for use with other unmanned transport vehicles (UxV), including for example and without limitation: unmanned aerial vehicles (UAV), unmanned surface vehicles (USV), and other autonomous ships, aircrafts, and vehicles.

The present system and method may also be employed in large-scale electrical power systems 100 which are part of non-mobile (stationary) facilities which require operations that are both autonomous and mission/context adaptable. The present system and method may also be employed in large-scale electrical power systems 100 which mobile, transportable power generation systems that are used to support various facilities at fixed sites at different times.
