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

System Control and Mode Switchings: In various exemplary embodiments, the present system and method may entail the use of integration of control systems or microcontrollers (MCU″) 527 for regulation of switches, capacitors, cooling systems, and other factors requiring real-time control. Such control systems 527 may entail the use of microprocessors, digital input/output elements, memory (such a random access memory (RAM) and various forms of non-volatile memory), display systems, audio input and/or audio signalling systems, and/or analogue control elements known in the art or to be developed. Such control systems 527 may employ suitable-coded software, stored in memory, to control various aspects of system operations.

In some embodiments, the MCU″ 527 may regulate, monitor, and/or control the microcontroller (MCUs) 227 of the A-PEBB LRUs 200.A; and/or regulate, monitor, and/or control the MCUs?327 of adaptable power stages A-PS 300 within the A-PEBB LRUs 200.A. Through suitable signalling and/or control mechanisms, the A-PEBB Power Converter 500 may dynamically and/or automatically change power conversion modes during field operations.

When and if solar PV power source is available, the exemplary A-PEBB converter 500 with multiple A-PEBB LRUs 200.A and microcontroller 527 can therefore be self-reconfigured to operate in a DC to DC mode to charge a battery system 110.B, or in a DC to DC or DC to AC mode to support loads or to interface with the grid (primary bus 110.1).
