Beschreibung
Zusammenfassung:	This voltage converter (106) comprises: - a grounding point (PM) intended to be connected to an electrical ground (M); - a high-voltage point (PHT) intended to have a high voltage (HT) relative to the electrical ground (M); - a low-voltage point (PBT) intended to have a low voltage (BT) relative to the electrical ground (M); - at least one voltage conversion cell (1081, 1082, 1083) connected to the grounding (PM), high-voltage (PHT) and low-voltage (PBT) points in order to perform a conversion between the high voltage (HT) and the low voltage (BT); and - a protection system (118) designed to detect a short circuit between the grounding (PM) and high-voltage (PHT) points and/or between the grounding (PM) and low-voltage (PBT) points. It further comprises a device (110) for measuring a ground current (IM) flowing between this grounding point (PM) and the electrical ground (M), and the protection system (118) is designed to detect the short-circuit based on the measured ground current (MIM).
