<p>The present invention relates a method and arrangement (1) for voltage protection of an electrical load (3) in a motor vehicle. A DC/DC converter (5) is arranged to receive as a control signal the voltage level on an electrical load (3) to be protected. The DC/DC converter (5) is arranged in a feed line (7) to the electrical load (3) to be protected in parallel with a diode (4). A battery (2) voltage of the vehicle is feed to an input of the DC/DC converter (5) and to the anode of the diode (4). The electrical load (3) to be protected is fed from the output of the DC/DC converter (5) and the cathode side of the diode (4).</p> |
