Abstract: A voltage source device includes a voltage converter configured to generate a supply voltage at an output node of the voltage converter. A current source is configured to apply a current to a first output terminal of the voltage source device in order to detect a cable voltage drop. A compensation circuit is configured to generate a feedback signal based on a voltage at the first output terminal. The supply voltage is generated based on the feedback signal.

Abstract: An embodiment of the present disclosure relates to a power supply interface comprising: a converter delivering a first DC voltage; a resistor connected between the converter and an output terminal of the interface delivering a second DC voltage; a first circuit delivering a second signal representative of a difference between the second DC voltage and a voltage threshold when a first signal is in a first state, and at a default value otherwise; a second circuit delivering a third signal representative of a value of a current in first resistor multiplied by a gain of the third circuit, and modifying the gain based on the second signal; and a third circuit configured to deliver a signal for controlling the converter based at least on the third signal.

Abstract: The present disclosure relates to an interface comprising: a terminal for delivering a DC voltage; a comparator for delivering a first signal representative of a comparison of the DC voltage with a high threshold; a comparator for delivering a second signal representative of a comparison of the DC voltage with a low threshold; and a circuit configured to: deliver successive pairs of values of high and low thresholds for a time period after the DC voltage crosses a first value of the low threshold; modify successive pairs of values of the thresholds based on the first and second signals to determine values of thresholds surrounding the DC voltage; and determining a current value of the DC voltage based on the values of thresholds surrounding the DC voltage.
