Abstract
A power supply arrangement having an interface for operation of a multi-voltage system of an agricultural vehicle includes a first network segment with a motor generator connected thereto and a second network segment with a lead battery connected thereto. The first network segment has a first voltage level corresponding to a nominal voltage of the lead battery for operation of an electric vehicle components, and the second network segment includes a higher second voltage level for charging the lead battery and providing electric power to an electric load comprising an agricultural implement. The interface forms a voltage source connecting the two network segments and provides an equalization voltage resulting from the two voltage levels in a charging mode and which is bypassed in a motor operating mode.
