AC/DC CONVERTER WITH GALVANIC INSULATION

摘要

The invention relates to an AC/DC converter that comprises at the input a rectifying circuit (2) connected in series to the primary winding (5) of an insulation transformer (6) and to a splitting switch (T1) connected to a pulse-width modulation control circuit (10), the insulation transformer including a first secondary winding (7) having a direction identical to that of the primary winding and connected to the output line (8) of the converter via a diode (D4), the output line being connected to an output capacitor (Cout), characterised in that the insulation transformer includes a second secondary winding (9) having a direction opposed to that of the primary winding and connected to the output line via a diode (D2).
