Abstract: A voltage measuring device includes an input configured to be coupled to a secondary of an inductive coupling of a DC to DC voltage converter. A switch coupled to the input forms a discharge path parallel to a sampling capacitor dependent on the voltage at the input equaling or exceeding a first voltage threshold and independent of an output voltage at the output of the device. The sampling capacitor is coupled to the output. A rectifier in series with the sampling capacitor is biased to conduct upon the input voltage, minus the output voltage, equaling or exceeding a second voltage.
