Abstract
Embodiments of the present invention provide a DC-DC converter having a first DC voltage gate, a second DC voltage gate and a storage choke. The storage choke is coupled between the first DC voltage gate and the second DC voltage gate by means of electric switching elements. The DC-DC converter is configured such that a direction of a current flow through the storage choke is inverted at least once during a switching period of the electric switching elements. Further, the DC-DC converter is configured to track or readjust a switching frequency of the electric switching elements in case of a change of operating parameters of the DC-DC converter such that a change of direction of the current flow through the storage choke during a switching period of the electric switching elements is ensured.
