SHORT CIRCUIT DETECTION DEVICE

The present description concerns a short-circuit detection device (100) in a direct current circuit comprising a voltage source (102), a bus comprising at least two conductive elements (104, 106) each coupled to one of the terminals of the voltage source, first and second thyristors (112, 114) coupled to the voltage source and to the bus, and at least one capacitive element forming a storage capacitor (118) each of whose electrodes is coupled to one of the two conductive elements of the bus, the short-circuit detection device comprising at least one control circuit (124) configured to control the biasing and operating modes of the first and second thyristors such that a short-circuit detection phase is implemented before a charging of the storage capacitor.
