Abstract
The disclosure relates to a method for operating a DC/DC voltage converter comprising a first switching bridge with at least two first switches coupled to an input of the DC/DC voltage converter, a second switching bridge with at least two second switches coupled to an output of the DC/DC voltage converter, a transformer and at least one capacitor, wherein the first switching bridge is connected to the second switching bridge via the transformer. The first switches are switched such that a resonant circuit formed by the transformer and the at least one capacitor is operated in resonance, and the second switches are switched at the same clock frequency with a phase shift compared to the first switches, such that the second switches are switched prior to the first switches. The disclosure also relates to a DC/DC voltage converter comprising a control circuit for the first and second switches which is configured to carry out the method, and to a backup power system including such a DC/DC voltage converter.
