Title:
VEHICLE WITH ELECTRICAL MACHINE AND METHOD FOR OPERATING THE SAME
Document Type and Number:
WIPO Patent Application WO/2013/131739
Kind Code:
A3
Abstract:
The invention relates to a vehicle having a multi-phase electrical machine, comprising a first partial on-board network (BN1') having a first nominal DC voltage and a second partial on-board network (BN2') having a second nominal DC voltage. According to the invention, the electrical machine has a rotor (7), a first stator system (5) and a second stator system (15), the first partial on-board network (BN1') comprising a first inverter (13) having a first intermediate circuit capacitor (11), wherein the first stator system (5) is associated with the first inverter (13), and the second partial on-board network (BN2') comprising a second inverter (14) having a second intermediate circuit capacitor (12), wherein the second stator system (15) is associated with the second inverter (14). The first stator system (5) is designed in a star circuit while the second stator system (15) is configured in a star connection or in a delta connection, and a transfer circuit (17a) connects the star point of the first stator system to the higher potential of the second partial on-board network (BN2').
