Discharge lamp starter circuit, connected in parallel with a lamp powered from an alternating current grid by an inductive stabilizer connected to the first electrode of the lamp, containing a thyristor key shunted with a diode, controlling the flow of current through the primary winding of a transformer, the first ending of whose secondary winding is connected to the common point of the winding of the stabilizer and the first electrode of the lamp, while between the second ending of the secondary winding of the transformer and the second electrode of the lamp is connected a circuit consisting of two capacitors connected in series, while parallel to the first capacitor connected to the second electrode of the lamp is connected a circuit in which the primary winding of the transformer is connected in series with the thyristor shunted with a diode, switched by a control circuit, whose first supply pole is connected to the common point of both capacitors while the second pole is connected to the second electrode of the lamp and/or to the cathode of the thyristor according to patent No. 153941, characterized in that it has an additional resistor (R) connected in series with the elements of an oscillatory circuit consisting of the first capacitor (C1), the primary winding (Z1) of the transformer (Tr), and the thyristor (Th) shunted with a diode (D).<IMAGE>
