1. A reconfigurable power circuit comprising:
- a first electrical connection interface and a second electrical connection interface;
a one-way DC to DC power converter comprising an input terminal for receiving input power at a first power amplitude and an output terminal for delivering output power at a second power amplitude;
a plurality of converter channel legs arranged as three different conductive pathways including a first bidirectional current flow path between the first electrical connection interface and the second electrical connection interface, a second, one-way current flow path extending from the first electrical connection interface to the input terminal through the one-way DC to DC power converter to the output terminal and from the output terminal to the second electrical connection interface, and a third one-way current flow path extending from the second electrical connection interface to the input terminal through the one-way DC to DC power converter to the output terminal and from the output terminal to the first electrical connection interface; and
at least one configurable switch disposed along each one of the plurality of converter channel legs wherein closing one or more first configurable switches and opening one or more second configurable switches enables exclusive current flow along one of the first bidirectional current flow path, the second, one-way current flow path, and the third one-way current flow path.

Abstract
A reconfigurable power circuit (400) includes a single one-way DC to DC power converter (220, 221). The reconfigurable power circuit is configurable by a digital data processor as one of three different power channels (230, 232, and 234). Power channel (230) provides output power conversion. Power channel (232) provides input power conversion. Power channel (234) provides bi-directional power exchange without power conversion.
