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.
