An electrical energy delivery device having a plurality of utilization units connected in strands, and methods of operating the energy delivery device

摘要

The invention relates to an electrical energy delivery device (10) having a plurality of utilization units (12), wherein each utilization unit (12) is adapted to generate or buffer electrical energy, and wherein a control device (19) is adapted to effect an energy exchange (E ) between the power delivery device (10) and at least one device (100). The invention provides that in the energy delivery device (10) the Nutzzeinheiten (12) divided into strands (11) and in each strand (11) whose Nutzzeinheiten (12) are connected to a series circuit (13) and the series circuit (13) via a DC-DC converter (14) and at least one galvanically separable switching unit (15) to a busbar assembly (18) of the power supply device (10) is connected and within each strand (11) for each use unit (12) a bypass circuit (N11) is provided and the control device (19) is arranged to control, for controlling the energy exchange (E), the DC-DC converter (14) and the at least one switching unit (15) of each string (11) and the bypass circuit (N11) of each use unit (12).
