A vehicle is provided with a multiphase electrical machine, a first onboard electrical sub-system having a first nominal DC voltage, and a second onboard electrical sub-system having a second nominal DC voltage. The electrical machine includes a rotor, a first stator system and a second stator system. The first onboard electrical sub-system includes a first inverter with a first link capacitor. The first stator system is associated with the first inverter. The second onboard electrical sub-system includes a second inverter with a second link capacitor. The second stator system is associated with the second inverter. The first stator system is configured in a star configuration. The second stator system is configured in a star configuration or in a delta configuration. A transfer circuit connects the star point of the first stator system to a higher potential of the second onboard electrical sub-system.
