Abstract
An embodiment of a controller for a multidirectional signal converter is operable to cause the converter to regulate a first signal at a first converter node, and to have a switch timing that is independent of a direction of power transfer between the first converter node and a second converter node. For example, in an embodiment, such a controller may be part of a bidirectional voltage converter that handles power transfer between two loads. Such a voltage converter may have improved conversion efficiency and a smaller size and lower component count as compared to a conventional multidirectional voltage converter. Furthermore, such a voltage converter may be operable with a common switching scheme regardless of the direction of power transfer, and without the need for an indicator of the instantaneous direction of power flow.
