Novel saturated iron core high-temperature superconductive current limiter served as harmonic suppressor

The invention discloses a novel saturated iron core high-temperature superconductive current limiter served as a harmonic suppressor. The novel saturated iron core high-temperature superconductive current limiter comprises two iron cores, wherein an alternating current superconductive winding and a direct current superconductive winding are arranged on each of the iron cores; the alternating current superconductive winding and the direct current superconductive winding on one of the iron cores are the same in winding direction; the alternating current superconductive winding and the direct current superconductive winding on the other iron core are opposite in winding directions; the superconductive current limiter comprises two circuits; an IGBT1 (Insulated Gate Bipolar Transistor 1), a direct current constant flow source I0, a resistor R1 and two direct current superconductive windings are connected on a direct current circuit in turn; an IGBT2 (Insulated Gate Bipolar Transistor 2), a current limiting resist
