A DC/DC converter (1) with a primary side (11) consisting of a resonant converter comprises a first and a second transformers (T1, T2), connected in series on the primary side (11) and on the secondary side (12) of the DC/DC converter. The secondary side (12) comprises an autotransformer (Tcd) consisting of a first and a second windings (Tcda, Tcdb) connected to a common center tap (Tcdc), where the first winding (Tcda) of the autotransformer (Tcd) is connected to the secondary winding (T1b) of the first transformer (T1), forming a first output connection point (P1), the secondary winding (Tcdb) of the autotransformer (Tcd) is connected to the second winding (T2b) of the second transformer (T2), forming a second output connection point (P2), and the center tap (Tcdc) of the autotransformer (Tcd) is connected to the positive output (21) of the secondary side (12). The secondary side (12) also comprises a first and a second rectifying switching devices (S1, S2), where the first rectifying switching device (S1) is connected between the first output connection point (P1) and the negative output (22) of the secondary side (12), and the second rectifying switching device (S2) is connected between the second output connection point (P2) and the negative output (22) of the secondary side (12). And a DC/DC converter system with at least two DC/DC converters is included. |
