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 various embodiments of the present system and method, and with various choices of A-PEBB LRUs 200.A along with suitable switch settings throughout, the loads can/may also be a propulsor (e.g., a rim driven motor/thruster or a pontoon-integrated/driven propeller), in which case the power required may be in a megawatt scale. Due to the modularity of the A-PEBB converter 500, multiple A-PEBB LRUs 200.A can be integrated and distributed around the rim of the propulsor/propeller, or inside the pontoons, to: (i) meet the propulsion power requirement while saving space, (ii) simplify service and maintenance (e.g., replacing A-PEBB LRUs), and (iii) provide for/enable a convenient and effective cooling thermal management (via water cooling from the ocean, sea, or river) for the A-PEBB converter 500.
