Electrical energy supply in front of the direction of the electrical drive arrangement and the on-board network with an electrical energy in the direction of providing

摘要

Disclosed is to provide an electrical energy in the direction (bv), comprising:– at least two power connections (pa, na);– an electrical power source (be) between the at least two electrical connections (pa, na);– a dc / dc converter (gw), which is disposed between the at least two electrical connections (pa, na) and the energy source (be) is electrically connected and is arranged, by means of a controllable semiconductor switch arrangement (hb1, hb2) and an inductance (l) of the dc / dc converter (gw) a between the at least two electrical connections (pa, na) applied input voltage (ua) into a voltage (ub) of the energy source (be) and / or is reversed to convert;– the semiconductor switch arrangement (hb1, hb2) in addition to the load switching - function is set up, in which the semiconductor switch arrangement (hb1, hb2) in an open switching state of a flow of current (i) between one of the at least two power connections (pa) and the energy source (be) interrupts;– a control arrangement (st), which is arranged to the interruption of the current flow (i1) between said one of the at least two power connections (pa) and the energy source (be) the semiconductor switch arrangement (hb1, hb2) in the open switching state is controlled to bring.
