Description

Technical Field

[0001] The utility model relates to the technical field of inductors, in particular to a PFC inductor. Background Art

[0002] An inductor is a component that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance, which only hinders the change of current. If there is no current flowing through the inductor, it will try to hinder the current from flowing through it when the circuit is connected; if there is current flowing through the inductor, it will try to maintain the current when the circuit is disconnected. Inductors are also called chokes, reactors, and dynamic reactors. Inductors can be made of conductive materials coiled around a magnetic core, typically copper wire. Traditional PFC inductor coils are wound using a whole copper wire.

[0003] However, the traditional PFC inductor is installed vertically on a fixed aluminum plate after copper wire is directly wound around the magnetic core. The coil and the aluminum plate are fixed by a steel belt. Since the magnetic core of this inductor is integrated, the magnetic core cannot be directly wound by a winding machine during winding, which makes the production inconvenient. Utility Model Content
