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

The present invention relates to the control of a DC-DC converter, wherein the gradient of a controlled variable is limited for the control of the DC-DC converter. A maximum current change in the DC-DC converter can be limited by limiting the gradient of the controlled variable in order to optionally prevent dangerous operating states of the DC-DC converter.

DC-DC converter and method for operating a DC-DC 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.
