Abstract

See full text

Examples provide a system and method for driving a DC-DC voltage with a primary-side full bridge and a transformer arranged between the primary-side full bridge and a secondary side of the DC-DC voltage converter. A first diagonal branch and a second diagonal branch are driven alternately. In a first switching sequence between driving the first diagonal branch and driving the second diagonal branch, the connecting elements of a primary side of the transformer are electrically connected to one another using the upper switching elements of the primary-side full bridge. In a second switching sequence between driving the first diagonal branch and driving the second diagonal branch, the connecting elements of the primary side of the transformer are electrically connected to one another using the lower switching elements of the primary-side full bridge. The primary-side full bridge is driven alternately according to the first switching sequence and the second switching sequence.
