An electrical apparatus for powering an electrical machine with two different energy sources includes an electrical drive system having a battery and a super capacitor, and an electrical machine, wherein the electrical machine includes a rotor, a first separate multi-phase stator winding and a second separate multi-phase stator winding, wherein the drive system includes a first multi-phase bridge inverter connected to the first multi-phase stator winding, and wherein the apparatus further includes a second multi-phase bridge inverter connected to the second multi-phase stator winding and to the battery, where the first multi-phase bridge inverter is connected to a super capacitor, and where the drive system includes a switch adapted to connect and disconnect the DC links of the first multi-phase bridge inverter to and from the second multi-phase bridge inverter. The super capacitor can be used to both deliver and absorb transient power peaks which can prevent the battery from exposure of the power peaks which can improve the battery life.
