- DC-DC converter 1 comprises a first input terminal El and a second input terminal E2. Between the first input terminal El and the second input terminal E2, an input voltage Uin can be applied. Optionally, a capacitance Cl may be provided between the first input terminal El and the second input terminal E2. Between the first input terminal El and a first node Kl, a first switching element Sl is arranged. Between the first
- a second switching element S2 is arranged. Furthermore, a third switching element S3 is arranged between the first node Kl and the second input terminal E2, and a fourth switching element S4 is arranged between the second node K2 and the second input terminal E2.

- the four switching elements S1 to S4 may be, for example, any semiconductor switching elements such as metal oxide field-effect transistors
- the DC-DC converter 1 comprises a transformer T having a primary side and a secondary side. A first terminal of the primary side of the transformer T is electrically coupled to the first node Kl and a second terminal of the primary side of the transformer T is electrically coupled to the second node K2. On the secondary side of the transformer T, an inductance LI is arranged between a first terminal of the transformer T and a third node K3. The third node K3 and a second terminal of the secondary side of
- Transformers T are electrically coupled to a rectifier circuit 10.
- This rectifier circuit 10 may be, for example, a passive bridge rectifier. Alternatively, it may be at the
- Rectifier circuit 10 also act to an active synchronous rectifier or the like.
- a fifth switching element S5 may be arranged between the third node K3 and a first output terminal AI of the rectifier circuit 10, which simultaneously also represents an output terminal of the DC-DC converter.

- Parallel to the fifth to eighth switching element S5-S8 can also be arranged in each case a freewheeling diode. Furthermore, a capacitance C2 can be provided between the first output terminal AI and the second output terminal A2.
- switching elements Sl to S4 and possibly S5 to S8 of the DC-DC converter 1 can be provided in this way between the first output terminal AI and the second output terminal A2, a predetermined target output voltage.
- the switching elements can be controlled by a control device 20 accordingly.
- the inventive control of the switching elements is described by way of example below.
- the inductance LI can be realized as a separate external component or optionally also as a leakage inductance of the transformer T.
- the inductance LI provides in particular a
- Resonant inductance of the DC-DC converter 1 and a leakage inductance of the transformer T is.
- Output terminal AI and the second output terminal A2 is charged via the closed switching elements S5 and S8.
- the closed switching elements S5 and S8 are the closed switching elements.
- the fourth switching element S 4 is initially opened, while the first switching element S 1 remains closed.
- the electric current commutates through the primary side of the transformer T of the fourth switching element S4 in the freewheeling diode parallel to the second switching element S2. Further, the electric current continues to flow through the closed first switching element Sl.
- the time interval t2 between the opening of the first switching element Sl (and the switching elements S5 and S8) should correspond to at least one dead time of the first switching element Sl. Due to parasitic effects of the components, in particular the switching elements Sl-S4, there may be a switching delay. By taking into account a dead time, which takes these properties into account, it can be ensured that no further electrical current will flow through the first switching element S1 when the further switching characteristics are initiated.
- the second switching element S2 and the third switching element S3 are then closed initially. Then, from the first input terminal El, an electric current flows through the second switching element S2, the primary side of the transformer T, and the third
- Switching element S3 to the second input terminal E2. Subsequently, an electric current is induced on the secondary side of the transformer T, and an electric current through the secondary side of the transformer T, the inductance LI and the two also closed switching elements S6 and S7 (sixth and seventh switching element) into the second capacitance C2. After a predetermined period of time, which preferably corresponds to the first time period t1 described above, the third switching element S3 is then opened. Then the electric current commutates through the freewheeling diode in parallel to the first switching element Sl.
- the corresponding switching element can be actively activated and closed in each case. In this way, it is possible the passage losses still continue to reduce, since the semiconductor electrical switching elements generally have lower losses than a parallel arranged freewheeling diode.
- the activation of the first switching element S1 to fourth switching element S4 takes place in a so-called "buck operation.”
- the time duration to be set for the freewheel that is to say the predetermined first time duration t1 depends on the output voltage to be provided, on a transmission ratio of Transformers T, the maximum
- Transmission ratio of the transformer T can be regarded as constant, with a limitation of the input current for the
- DC converter 1 to a maximum value are assumed that the output voltage Uout of the DC-DC converter is directly proportional to the first time interval tl for the freewheel. This allows a particularly simple control of the output voltage Uout.

- the DC-DC converter for this method may in particular be a DC-DC converter 1 described above.
- step 110 the second switching element S2 and the third switching element S3 are opened.
