AI summary
Techniques are provided for correctly associating a feedback port of a DC-DC voltage converter system and a DC power output port of the DC-DC voltage converter system. By having a correct association, measurement data from a measurement sensor coupled through a set of electrical conductors to a DC-DC voltage converter are fed back to a processing system and used to control a DC voltage level provided by the DC-DC voltage converter to accurately regulate a DC voltage at radio ends of the set of electrical conductors. Alternatively, a resistance of the set of electrical conductors is determined using regression and without such association. Both the resistance and a measured current, drawn from a DC power output electrically and through first ends of the set of electrical conductors to the radio ends, can be used to accurately regulate the DC voltage at the radio ends.
