The power supply apparatus (10) comprises an input (12), first and second outputs (14, 16) and means (18) for conversion of the electric current which are connected between the input (12) and the outputs (14, 16). The conversion means (18) comprise a transformer (20) comprising a primary winding (20A) supplied by the input electric current and first and second secondary windings (20B, 20C) respectively supplying the first and second outputs (14, 16) by way of first and second shaping circuits (22, 24). The first shaping circuit (22) comprises regulating means (48) adapted to act on the electric current feeding the primary winding (20A). The regulating means (48) are adapted to effect regulation in dependence on a signal from the first shaping circuit (22). The second shaping circuit (24) comprises autonomous means (86, 88) for regulating the current provided by the second output (16).
