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

CRJ 380.A.1, CRJ 380.A.2: For another example, the paired circuit nodes 280.3, 280.4 of I-PS 210 (which may be viewed as topologically analogous to CRJ connections 380.A.1, 380.A.2 of A-PS 300) provide for only fixed current routing. By contrast, the CRJ connections 380.A.1, 380.A.2 of RH-BC 320 provide provision for multiple connections to exemplary CFC module 375.3. CFC module 375.3 in turn has an inductor L1, and six contactors 350 (SW3, SW4, SW5, SW16, SW8, SW9), which can be set in a variety of combinations of open/closed settings 395 to achieve various current routings within A-PS 300; and further thereby to achieve various different operational conversion modes CM 392 for A-PS 300. Exemplary operational modes 392 and contactor settings 395 are discussed further below in conjunction with FIG. 3C.

It will be noted that many elements of A-PS 300 are exemplary only. These include the number and location of the current routing junctions (CRJ) 380; and the internal elements and configurations of the CFC modules 375. In alternative embodiments, an A-PS 300 may employ more, fewer, or alternative CRJs 380; and may similarly employ more, fewer, or different CFC modules 375 with different internal components or arrangements of components. Persons skilled in the relevant arts will appreciate that such alternative embodiments may entail variations in the operational modes discussed above and also below in conjunction with FIG. 3C.
