A drive device for use in a vehicle includes a motor, a substrate, and at least one inter-system ground connection capacitor. The motor includes a plurality of motor windings within one housing. Multiple inverters are mounted on the substrate. Each inverter is connected to a different battery and a different ground to form a system, where each of the motor windings is associated with its own system. The inter-system ground connection capacitor is mounted on the substrate, and electrically connects the grounds of the systems together to reduce electrical noise propagated outside the drive device to other parts in the vehicle.
