BIDIRECTIONAL SIGNAL CONVERSION

摘要

An embodiment includes coupling a first intermediate node between a first inductor and a first winding of a transformer to a reference node during a first portion of a first switching cycle, uncoupling the first intermediate node from the reference node and coupling the first intermediate node to a signal storage element during a second portion of the first switching cycle, coupling a second winding of the transformer between the reference node and a second converter node during the second portion of the first switching cycle, and regulating a signal at the second converter node by controlling a duration of one of the first and second portions of the first switching cycle. For example, in an embodiment, bidirectional signal converter may perform the above steps to handle 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 bidirectional 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.
