Abstract: An electrical circuit arrangement includes a traction battery, electrical connection for electrically coupling to a vehicle-external electric unit, and first and second high-voltage potentials. The circuit arrangement has two electric drive units each having an inverter and an electric three-phase motor electrically coupled thereto for driving the vehicle. The circuit arrangement is configured such that the two electric drive units can be electrically connected in series between the electrical connection and the traction battery such that the first electric drive unit increases the first high-voltage potential and the second electric drive unit increases the second high-voltage potential from the electrical connection to the traction battery. The inverters each have a capacitor between a potential line of the first high-voltage potential and a potential line of the second high-voltage potential.

Abstract: A vehicle includes a traction battery, a drive unit having a three-phase motor and an inverter electrically coupled to the three-phase motor, the inverter being electrically coupled to the traction battery, and a charging connection for electrically coupling to a vehicle-external DC charging station. The inverter is a flying capacitor inverter.

Abstract: A component arrangement for an electric high-voltage on-board power supply of a vehicle includes a shared EMC filter, a shared intermediate circuit, a plurality of electrical components, and a shared housing. The shared EMC filter and the shared intermediate circuit are provided for the plurality of electrical components. The plurality of electrical components are disposed in the shared housing together with the shared EMC filter and the shared intermediate circuit. The plurality of electrical components are interconnected in parallel with the shared intermediate circuit and the shared EMC filter and there is otherwise no electrical connection between them.

Abstract: A direct current converter includes a plurality of direct current converter modules having electrical input voltages and output voltages that differ from each other. The plurality of direct current converter modules are electrically connectable to one another to form a plurality of subsystems such that a high-voltage electrical voltage is convertible into different low-voltage electrical voltages. The plurality of direct current converter modules are configured as a shared integrated assembly. At least one of the plurality of subsystems is always active.
