Beschreibung
Zusammenfassung:	A power circuit common mode filter includes: a U-shaped soft magnetic core and two cylindrical soft magnetic cores, wherein recessed grooves are provided at tops of two side walls of the U-shaped soft magnetic core, and the two cylindrical soft magnetic cores are movably installed in the U-shaped soft magnetic core; two ends of each of the cylindrical soft magnetic cores are embedded in the corresponding recessed grooves, and a coil is set on each of the two cylindrical soft magnetic cores in the U-shaped soft magnetic core; the U-shaped soft magnetic core and the cylindrical soft magnetic cores are both covered with a high-voltage-resist insulating material to form insulating layers; surfaces of the insulating layers at the recessed grooves are provided with electrode layers, and ends of the coil is fixedly connected to the electrode layers through soldering tin.
