COMPOUND TYPE REACTOR

PROBLEM TO BE SOLVED: To provide a compound type reactor that can reduce magnetic flux leakage occurring around it.SOLUTION: The magnetic core of a compound type reactor comprises a first core part around which a first coil is wound and a second core part around which a second coil is wound. The first and second coils, which are arrayed with the magnetic core as the common core, have a first wound part and a second wound part together with a third wound part and a fourth wound part, each pair being split-wound around a different central axis of the coils. The first wound part and the second wound part on one hand and the third wound part and the fourth wound part on the other are arrayed in such directions that magnetic fluxes interlinking around the first and second coils cancel each other. In the first wound part and the second wound part respectively split-wound around the first and second coils and in the second core part caused to oppose the first core part by the third wound part and the fourth wound part, the directions of magnetic fluxes are reverse to each other.SELECTED DRAWING: Figure 3 【課題】周囲に発生する漏れ磁束を低減可能な複合型リアクトルを提供すること。【解決手段】複合型リアクトルの磁性コアは、第１コイルの巻線が巻回される第１コア部と、第２コイルの巻線が巻回される第２コア部とを有する。磁性コアを共通コアとして配設される第１、第２コイルは、異なる巻線中心軸上にそれぞれ分割巻きされた第１巻線部及び第２巻線部と、第３巻線部及び第４巻線部とを有する。第１巻線部及び第２巻線部並びに第３巻線部及び前記第４巻線部は、第１、第２コイルの周囲で鎖交する磁束が互いに打ち消し合う向きにそれぞれ配設される。第１、第２コイルのそれぞれ分割巻きされた第１巻線部及び第２巻線部と第３巻線部及び第４巻線部による、第１コア部と相対する第２コア部における磁束の向きは相反する。【選択図】図３
