To provide a supply device for a motor vehicle.SOLUTION: In a supply device (10), a DC/DC converter (20) is configured, in a first state, to enable a conversion of a first DC voltage (U1) at first terminals (23, 24) into a lower second DC voltage (U2) at second terminals (25, 26) and, in a second state, to carry out no conversion of a first DC voltage (U1) at the first terminals (23, 24) into a lower second DC voltage (U2) at the second terminals (25, 26). A control device (22) enables an energy supply at the second terminals (25, 26) by repeatedly changing the DC/DC converter (20) bidirectionally between the first state and the second state.SELECTED DRAWING: Figure 1

    【課題】自動車のための供給装置を提供する。【解決手段】供給装置(10)において、DC/DCコンバータ(20)は、第1の状態において、第1の端子(23、24)における第1のDC電圧(U1)を第2の端子(25、26)におけるよりも低い第2のDC電圧(U2)に変換することを可能にし、かつ、第2の状態において、第1の端子(23、24)における第1のDC電圧(U1)を第2の端子(25、26)におけるよりも低い第2のDC電圧(U2)に変換しない。制御装置(22)は、第1の状態と第2の状態との間で双方向にDC/DCコンバータ(20)を繰り返し切り換えることにより、第2の端子(25、26)でのエネルギー供給を可能にする。【選択図】図1
