Plane magnetic cores structure of three -phase AC differential mode and common mode integration

The utility model relates to an electric system passive component technical field especially relates to a plane magnetic cores structure of three -phase AC differential mode and common mode integration. It includes four magnetic core modules, and first magnetic core module, second magnetic core module, third magnetic core module and fourth magnetic core module are in the coplanar, second magnetic core module, third magnetic core module, fourth magnetic core mould splits leave and first magnetic core module one end is connected. Through optimizing magnetic cores structure, make interchange differential mode and common mode magnetic device realize in planar structure that magnetism is integrated to make its problem that can effectively improve filtering and anti common mode interference, unbalanced three phase, improve the dc magnetic biasing and restrain the ability and can reduce reactor volume and weight simultaneously, and then reduced overall cost.
