ELECTRIC DRIVE SYSTEM |
摘要 |
The invention relates to an electric drive system, comprising an n-phase electric machine, n>1, which has at least two single-phase winding strands, a first inverter, the output connection of which is connected to the phase connection of a first of the single-phase winding strands of the electric machine, at least one second inverter, the output connection of which is connected to the phase connection of a second of the single-phase winding strands of the electric machine, and a DC voltage source which has a plurality of series-connected battery modules and the output connections of which are respectively connected to the input connections of the first inverter and to the input connections of the second inverter, so that the first inverter and the second inverter are arranged in parallel. |
