Abstract

The invention relates to the technical field of power electronics, and provides a three-phase inductor and a power module. The current flowing through each inductor comprises a power frequency currentcomponent and a high frequency current component. The three-phase inductor comprises a magnetic core and a winding, the magnetic core comprises a first cover plate, a second cover plate and a magnetic column unit, the first cover plate and the second cover plate are oppositely arranged, and the magnetic column unit is clamped between the first cover plate and the second cover plate; the first winding is wound on the first magnetic column and the second magnetic column of the first magnetic column unit, and a first current flowing through the first winding surrounds the first magnetic column and the second magnetic column in opposite directions; the second winding is wound on the first magnetic column and the second magnetic column of the second magnetic column unit, and a second current flowing through the second winding surrounds the first magnetic column and the second magnetic column in opposite directions; and the third winding is wound on the first magnetic column and the secondmagnetic column of the third magnetic column unit, and a third current flowing through the third winding surrounds the first magnetic column and the second magnetic column in opposite directions.

Description

technical field [0001] The present disclosure relates to the technical field of power electronics, in particular to a three-phase inductor and a power module. Background technique [0002] At present, in high power density power modules, the volume, weight and loss of inductors account for a large proportion, so the status of inductors is becoming more and more important. [0003] Especially in a power module involving multiple inductors, the multiple inductors are often set independently, resulting in a large overall inductor size, which is difficult to apply to a power module with a high degree of integration. Contents of the invention [0004] A main purpose of the present disclosure is to overcome at least one defect of the above-mentioned prior art, and provide a three-phase inductor and a power module. [0005] According to the first aspect of the present invention, a three-phase inductor is provided, the current flowing through each inductor includes a power freque...
