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

Redundancy and Self-Healing: The exemplary A-PEBB converter 500 inherently has built-in redundancy. During a mission, any failed/malfunctioning A-PEBB LRUs 200.A can be bypassed to keep the converter 500 running, or to maintain converter-based power distribution operation with equivalent or reduced/de-rated capacity. Further Depending on the health conditions and availability of sources and loads during a mission, the A-PEBB converter 500 can be re-configured or re-purposed to optimize/maximize the operation of the remaining available assets. This “self-healing” adaptability can help provide for power distribution with field survivability when the power system 100 is employed in in conflict missions or hostile environments (where some sources and loads may be damaged or become unavailable). The self-reconfigurability is also useful in fully utilizing NOMARS (or other mobile system) onboard assets in normal operating conditions. For example, during a shiny day, an A-PEBB converter 500 can be configured to convert solar PV energy (if present) to support loads or to charge the electrical system 100 during the day. The A-PEBB converter 500 can then be re-configured or repurposed to interface with other available sources (generators or batteries) to support loads at nights.

Above, exemplary embodiments of the present system have been presented with exemplary components of various power, current, and/or voltage ratings. Other power/current/voltage ratings may be employed within the scope of the appended claims.
