Abstract: Disclosed is a method for calibrating an AC/DC converter with power factor correction, including the following steps: - connecting the input connector of the converter to a predetermined DC voltage power supply, such that this predetermined DC voltage is applied between the terminals of the input connector; - measuring, with a voltage measuring unit, the resulting calibration DC voltage which is delivered by the switching module when the predetermined DC voltage is applied between the terminals of the input connector; and -calibrating the voltage measuring unit by performing a calibration bringing the resulting calibration voltage back to the level of the predetermined DC voltage.
