Zusammenfassung:The invention provides an integrated magnetic element, a PFC circuit and electronic equipment. The integrated magnetic element comprises a magnetic core, a main coil and a secondary coil, the magnetic core comprises two oppositely arranged first side columns, a middle column and two oppositely arranged second side columns, the two first side columns and the two second side columns form a magnetic loop, and the two ends of the middle column are connected with the middles of the two second side columns respectively; the main coil is wound on the two first side columns and the middle column respectively; the secondary coils are respectively wound on the two first side columns; wherein the winding direction of the main coil is the same, and the winding direction of the secondary coil is opposite to the winding direction of the main coil. According to the integrated magnetic element provided by the invention, the cost can be reduced, and the problem of three-phase imbalance of the integrated magnetic element is so
