The voltage stabilization of additional outputs of converters is provided with high precision by means of an adjusting circuit wherein a current traverses a storage capacity (26) and the primary winding (32) of a transformer (72). The secondary winding (33) of said transformer (72) is coupled by one of its ends and through a diode (34) to the primary winding and through another diode (35) and a switching element (36) with its other end. The switching element (36) is controlled by a comparator (38) which compares the voltage at the terminals (40, 41) to a reference voltage. When the output voltage is below a predetermined value, the element (36) is shunted and the voltage value on the capacity (26) is maximum. If the voltage value is equal or higher, the switching element (36) becomes non-conductor and the current induced in the secondary winding (33) reduces the current which flows from the winding (8) of the transformer to the capacity (26) in an amount inversely proportional to the relation between the primary winding (32) and the secondary winding (33). |
