Abstract:
1. A method for compensating a voltage regulator output for a voltage drop along one or more conductors conducting current between one or more output terminals of the regulator and a load comprising: operating the regulator in a first mode of operation to output, at the one or more output terminals of the regulator, a regulated first voltage at a first current drawn by the load; operating the regulator in a second mode of operation by temporarily changing the output of the regulator to cause the regulator to output a second voltage and second current; detecting a difference between at least the first voltage and the second voltage, or between the first current and the second current, to determine a first signal corresponding to a fractional voltage drop along the one or more conductors between the regulator and the load; computing, by using the first signal, a compensation voltage substantially corresponding to a full voltage drop along the one or more conductors when the regulator operates in the first mode of operation; and operating the regulator in the first mode while using the compensation voltage to compensate the output voltage of the regulator for the full voltage drop.
