A vehicle electrical system comprises a first low voltage electrical circuit 101 and a second high voltage electrical circuit 102, both receiving power simultaneously from a mechanically driveable switched reluctance generator 122. The circuits each have separate grounds 107, 108 that are electrically isolated from each other, but the low voltage and high voltage circuits are still able to communicate data through an isolation unit 120 comprising optoisolators and galvanic barriers. The generator 122 may be operated as either a motor or a generator and when generating produces high voltage power. A step down voltage converter 131 allows this power to be used by low voltage devices 105. The first electrical ground 107 may be the vehicle body and the second electrical ground 108 may be a terminal insulated from the casing of the mechanically driveable generator 122. |
