Abstract
The present invention relates to a device (100) and a method for supplying an electric drive (101) with electric current. For this purpose, three DC/DC converters (102, 103, 104) are provided for coupling at least two connectable electric energy sources (105, 106) to the electric drive (101). The DC/DC converters (102, 103, 104) can be coupled in such a way that direct coupling of each individual one of the at least two electric energy sources (105, 106) to the electric drive (101) is formed via an individual one of the three DC/DC converters (102, 103, 104).
Claims12
A device (100) for supplying electric current to an electric drive (101), comprising three DC-to-DC converters (102, 103, 104), coupled in a ring formation, for coupling at least two connectable electrical energy sources (105, 106) to the electric drive (101), characterized in that the DC-to-DC converters (102, 103, 104) are couplable in such a way that a direct coupling of each individual one of the at least two electrical energy sources (105, 106) to the electric drive (101) is formed via a single one of the three DC-to-DC converters (102, 103, 104);
- wherein the DC-to-DC converters (102, 103, 104) are couplable such that a direct coupling of the at least two electrical energy sources (105, 106) via one of the three DC-to-DC converters (102, 103, 104) is formed.
A method (400) for supplying electric current to an electric drive (101), wherein three DC-to-DC converters (102, 103, 104), coupled in a ring formation, are provided for coupling at least two connectable electrical energy sources (105, 106) to the electric drive (101), characterized in that the DC-to-DC converters (102, 103, 104) are coupled (402) in such a way that each individual one of the at least two electrical energy sources (105, 106) is coupled directly to the electric drive (101) via an individual one of the three DC-to-DC converters (102, 103, 104), and wherein the DC-to-DC converters are coupled (403) in such a way that the at least two electrical energy sources (105, 106) are coupled directly via one of the three DC-to-DC converters (102, 103, 104).
