Abstract

Disclosed example polarity reversing buck converter circuit include: a first bus node configured to receive a first DC voltage a second bus node; first and second output terminals; a first switching device configured to selectively couple the first output terminal to the first bus node; a second switching device configured to selectively couple the first output terminal to the second bus node; a third switching device configured to selectively couple the second output terminal to the first bus node; a fourth switching device configured to selectively couple the second output terminal to the second bus node; and control circuitry configured to: control the third and fourth switching devices to couple the second output terminal to the first or the second bus node, based on a selected output polarity; and based on the selected polarity, control the first and second switching devices to perform DC-DC conversion.
