Thyristor power supply with current regulation, in particular for demagnetising lifting magnets, containing a phase-controlled two-way rectifier connected on one side to the coil of the lifting magnet, and on the other side via a demagnetising pulse generator to a DC source, characterized in that the demagnetising pulse generator (C) is connected via back coupling to a controlled voltage source (F), and also contains an element (E) generating demagnetising pulses, while the circuit connecting the phase-controlled two-way rectifier (A) to the coil of the lifting magnet (G) contains a two-way current detector (B) additionally coupled to the element (E) generating the demagnetising pulses of the demagnetising pulse generator (C).<IMAGE>
