A dual active bridge converter is provided with a control variable that is superimposed with an additional ripple component to control the dual active bridge converter with a combination of the control variable and the additional ripple component.

Dual active bridge converter, voltage converter arrangement and method for operating a dual active bridge converter

A method for a phase-shifted full-bridge DC-DC converter. The method controls the DC-DC converter for energy transmission from a secondary side to a primary side of the DC-DC converter. A transformer is arranged between the primary side and the secondary side of the DC-DC converter. The method comprises a switching state, in which the terminals of the primary side of the transformer are electrically connected to one another, and in which, furthermore, the terminals of the secondary side of the transformer and the terminals of the secondary side of the DC-DC converter are electrically connected to one another.

Control method for a DC-DC converter and dc-dc converter

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.

Drive method for a DC-DC voltage converter, and DC-DC voltage converter

The invention relates to a transformer core with at least one additional leg. Said additional leg is used to form a leakage path. In order to optimize the installation space and for easier connection of the transformer windings, the transformer legs and the additional leakage path legs are not arranged along a common line.
