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.

The invention also relates to a method for operating a power converter. The method comprises the step of controlling multiple switches of the power converter using a control unit, which is connected to the multiple switches, based on data in a database using an input parameter or an output parameter.

Power converter and method for operating a power 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 present invention relates to a circuit arrangement and to an actuating method for a DC voltage converter, in particular a DC voltage converter with phase-shifted full-bridge topology, wherein power can also be transmitted from the primary side to the secondary side when the electrical voltage on the primary side undershoots the product of the electrical voltage on the secondary side and the transmission ratio of a transformer in the DC voltage converter. In this way, for example, a capacitor on the primary side of the DC voltage converter can be discharged to a safe, low voltage level.
