Embodiment Construction

[0013] The accompanying drawings disclose the basic structure of the present invention without limitation, and the present invention will be further described below in conjunction with the accompanying drawings.

[0014] figure 1 It is a schematic diagram of a two-phase differential mode and a common mode reactor. The two-phase coils are double-wired and wound on the central core to realize a common-mode reactor; after the two wires are separated, they are respectively wound on other cores to realize a differential-mode reactor. . figure 2 It is a schematic diagram of a three-phase differential mode and common mode reactor. The three-phase coil and three wires are wound on the central core column to realize a common mode reactor; after the three wires are separated, they are respectively wound on other core columns to realize a differential mode reactor.

Abstract

The invention discloses a multi-phase differential-mode and common-mode joint reactor, which consists of multiple phases of coils and a space-symmetrical multi-stem iron core, wherein the iron core is provided with a central stem; the central stem serves as a symmetric center and the other stems are distributed symmetrically in a geometric form; a part of each coil of the multi-phase reactor is wound on the central stem with the same number of turns in the same direction so as to form a common-mode part of the multi-phase reactor; and the coils are separated and each coil is wound on the other stems respectively so as to form the differential-mode part of the multi-phase reactor. The multi-phase differential-mode and common-mode joint reactor can effectively improve filtering and anti-jamming performance, and has wide application prospect.

Description

Technical field: [0001] The invention relates to a reactor, which belongs to electrical components, in particular to a multi-phase differential mode and common mode integrated reactor. Background technique: [0002] Existing differential-mode reactors and common-mode reactors exist as a single body, and so far there is no integrated differential-mode and common-mode reactor. Invention content: [0003] The object of the present invention is to propose a reactor integrating multi-phase differential mode and common mode. [0004] The realization method of the present invention: the multi-phase differential-mode and common-mode integrated reactor is composed of multi-phase coils and a spatially symmetrical multi-stem iron core; the iron core has more than three stems, and there is a central stem in the stem , taking the central core column as the symmetrical center, and the rest of the core columns are geometrically symmetrically distributed; each phase coil of the multiphas...
