AC/DC converter supplied by a constant voltage (Vg) applied between two input terminals (A, B) to produce a constant direct current on a load (RL) connected between two output terminals (C, D). The converter includes an input circuit and an output one, having galvanic insulation between them and formed by inductors magnetically coupled among them (L1A, L1B; L2A, L2B) and bidirectional switching means (Q1, Q2) driven by pulse signals having constant repetition frequency and variable duration depending on the load and on the A.C. (Vg) to be rectified. |
