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.
