Abstract

The invention relates to a vehicle having a multiphase electric machine, comprising a first onboard power subsystem provided with a first nominal DC voltage level, and a second onboard power subsystem provided with a second nominal DC voltage level, wherein the electric machine comprises a rotor, a first stator system, and a second stator system. The first onboard power subsystem comprises a first inverter having a first intermediate circuit capacitor. The first stator system is dedicated to the first inverter. The second onboard power subsystem comprises a second inverter having a second intermediate circuit capacitor, and the second stator system is dedicated to the second inverter. The first stator system is configured in a star connection, the second stator system is configured in a star connection, and a transfer circuit connects the star point of the first stator system to the star point of the second stator system.
