Triphase AC/DC converter, supplied by a triphase system of alternate voltages (Vr, Vs, Vt) triangularly connected among the input terminals (A, B, C) of the converter to produce a direct output voltage on a load (RL) connected between two output terminals (D, E). The converter includes an input circuit (IN) and an output one (OUT), having galvanic insulation among them and formed by inductors magnetically coupled among them (L1A, L1B; L2A, L2B; L3A, L3B) and bidirectional switching means (Q1, Q2, Q3) driven by pulse signals (G1, G2, G3) having constant repetition frequency and varialbe duration depending on the load (RL) and on the triphase voltage circuit to be rectified. |
