A vehicle drive arrangement is controlled with an actuator arrangement. The DC voltage converter comprises at least two diodes, one switch and one storage choke which is charged by the DC voltage generator when the switch is closed and is discharged via the capacitors and the diodes when the switch is open. Further, the polymer compositions are reactor grade compositions comprising a reactor blend of a first polymer and a second polymer, preferably where both of the first and second polymers are prepared using the same catalyst system.
