摘要： 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.

摘要： 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.

摘要： The present invention relates to a power transmission in a DC-DC converter, in particular a phase-shifted full-bridge DC-DC converter from the secondary side to the primary side. In particular, an additional switching state which can reduce the power dissipation of the switching elements in the DC-DC converter, is provided.
