    Abstract: A power converter is connectable to a computer device 20 that requires a stable input voltage v1 by a coupling circuitry 30 and comprises a voltage regulator 11 controlling an actual output voltage v2 based on an output reference voltage v3. The output reference voltage v3 is determined and equals a sum of the stable input voltage v1 and the product of the resistance R30 of the coupling circuit 30 and the current I1 measured at the output of the voltage regulator. Coupling circuit 30 can comprise serial wires and connectors and be the sole connection between the converter and the computer device. The output reference voltage v3 can be determined using a temperature compensated resistance of the coupling circuit that can be based on an ambient temperature measurement (fig 4, 17) and a stored temperature compensation model. There can be plural groups of computer devices each group having a regulator for which the output reference voltage v3 is determined as the sum of the input voltage v1 for the group and the product of coupling circuit resistance and measured current of the group. The stable input voltage,v1, the resistance R30 and the temperature compensation model may be stored in a memory that is queried to calculate the reverence voltage.
