Description

本考案は複合式コモンモードコイルに関する。特に2個のコイル間に鉄芯を設置し、しかも鉄芯側面の表面積は調整可能である複合式コモンモードコイルに係る。   The present invention relates to a composite common mode coil. In particular, the present invention relates to a composite common mode coil in which an iron core is installed between two coils and the surface area of the side surface of the iron core is adjustable.

近年ハイテク技術の発展は目覚しく、特にマイクロエレクトロニクス関連技術の製造プロセス領域では日進月歩の発展が続いている。電子関連製品は各家庭及び各業界に深く浸透しているため、現代生活においてなくてはならないものになっている。しかし、人類の要求には限度がないため、電子装置はより多くの機能性が要求され、機能は多元化に向って行る。各種電子設備、ビデオインターネット、交換機、携帯式通信設備、オフィスの自動化の普及に従い、電子システム中の電磁環境はどんどん複雑になっており、電磁干渉(EMI)現象も日増しに深刻になり、しかもシステムの正常な作業に影響を及ぼす明確な障害となっている。   In recent years, the development of high-tech technology has been remarkable, especially in the manufacturing process field of microelectronics-related technology. Electronic products are indispensable in modern life because they are deeply penetrated into each home and industry. However, since there is no limit to human requirements, electronic devices are required to have more functionality, and the functions are directed toward multiple factors. With the widespread use of various electronic equipment, video internet, exchanges, portable communication equipment, and office automation, the electromagnetic environment in electronic systems has become increasingly complex, and the electromagnetic interference (EMI) phenomenon has become increasingly serious. It is a clear obstacle that affects the normal operation of the system.

一般的な交換式電源において、主なEMI干渉源の多くはパワー半導体部品の切り替え動作である。EMI干渉源の多くはコモンモードノイズと差動モードノイズを備えるため、発生する電磁発射(EME、Electromagnetic Emission)は通常はブロードバンドのノイズで、その周波数範囲は交換作業周波数から数MHzまでである。公知の変圧器はコモンモードノイズと差動モードノイズを克服する為にコモンモードチョック及び差動モードチョックを設計けるのである。しかしながり、公知の変圧器2は体積が大きく、製造が容易でないため、製造コストを増大させている。これは当業界が解決を迫られている目下の急務である。   In a general exchangeable power supply, many of the main EMI interference sources are switching operations of power semiconductor components. Since many EMI interference sources have common mode noise and differential mode noise, the generated electromagnetic emission (EME) is usually broadband noise, and its frequency range is from the exchange work frequency to several MHz. Known transformers can design common mode and differential mode chocks to overcome common mode and differential mode noise. However, since the known transformer 2 has a large volume and is not easy to manufacture, the manufacturing cost is increased. This is an immediate urgent need for the industry to resolve.

本考案が解決しようとする第二の課題は、差動モード方式設計をコモンモード方式設計に代えることで、体積と製造コストを減少させることができるコモンモードコイルを提供することである。
The first problem to be solved by the present invention is that an iron core is installed between two coils, and the surface area of the iron core side surface can be adjusted, thus the common mode coil modifies the magnitude of the leakage inductance. Can
The second problem to be solved by the present invention is to provide a common mode coil that can reduce the volume and the manufacturing cost by replacing the differential mode system design with the common mode system design.

図1、図2を参照されたい。本考案の複合式コモンモードコイル1は底台11、コイル積載体12、鉄芯体13を含む。該底台11は2個の設置槽111、少なくとも1個の固定槽112、少なくとも1個の隔離槽113を備える。該隔離槽113は該2個の設置槽111間に位置し、該設置槽111はおよそ円柱形状を呈し、しかも該固定槽112は該設置槽111の軸方向にほぼ垂直である。   Please refer to FIG. 1 and FIG. The composite common mode coil 1 of the present invention includes a base 11, a coil loading body 12, and an iron core body 13. The base 11 includes two installation tanks 111, at least one fixed tank 112, and at least one isolation tank 113. The isolation tank 113 is located between the two installation tanks 111, the installation tank 111 has an approximately cylindrical shape, and the fixed tank 112 is substantially perpendicular to the axial direction of the installation tank 111.

該コイル積載体12は2個の積載板体121、2個の柱体122、2個のコイルラック123を含む。該積載板体121はおよそ矩形立体構造を呈し、該積載板体121の形状は該固定槽112の形状と相互に対応し、しかも該固定槽112は該積載板体121を設置する。該柱体122はおよそ円柱形状を呈し、しかも該柱体122の両端はそれぞれ該積載板体121と相互に連接する。本考案のコイルラック123は半コイルラック1231、1232が対応接続し形成し、しかも該2個の半コイルラック1231、1232は相互に連接し設置空間1233を形成する。該設置空間1233の形状はおよそ該柱体122の形状と相互に対応する円柱形状である。よって、該コイルラック123は該2個の半コイルラック1231、1232により対応接続し形成後、該コイルラック123の外縁は複数のコイル1234が巻き付き、しかも該2個のコイルラック123は該設置槽111中に一つ一つ対応設置される。   The coil loader 12 includes two load plates 121, two pillars 122, and two coil racks 123. The loading plate 121 has a substantially rectangular three-dimensional structure, and the shape of the loading plate 121 corresponds to the shape of the fixed tank 112, and the fixed tank 112 is provided with the loading plate 121. The column body 122 has a substantially cylindrical shape, and both ends of the column body 122 are connected to the loading plate body 121. The coil rack 123 of the present invention is formed by correspondingly connecting half-coil racks 1231 and 1232, and the two half-coil racks 1231 and 1232 are connected to each other to form an installation space 1233. The installation space 1233 has a cylindrical shape corresponding to the shape of the pillar 122. Therefore, after the coil rack 123 is formed by correspondingly connecting the two half-coil racks 1231 and 1232, a plurality of coils 1234 are wound around the outer edge of the coil rack 123, and the two coil racks 123 are installed in the installation tank. 111 is installed one by one.

該鉄芯体13は矩形の立体構造で、しかも該鉄芯体13は導磁率が高い材質により製造する。本考案の鉄芯体13は相互に対応する2個の側面131を備え、該側面131の表面積は長さ1311と高さ1312を掛けて定義する。該高さ1312の方向は該隔離槽113の延伸方向とほぼ垂直である。本考案の最適実施例において、該鉄芯体13は該隔離槽113中に位置し、しかも該側面131により該コイルラック123に隣接する。   The iron core 13 has a rectangular three-dimensional structure, and the iron core 13 is made of a material having a high magnetic conductivity. The iron core body 13 of the present invention has two side surfaces 131 corresponding to each other, and the surface area of the side surface 131 is defined by multiplying the length 1311 and the height 1312.

該コイルラック123中の複数のコイル1234にそれぞれ電流が流れると、該2個のコイルラック123間には漏電インダクタンスを形成する。よって該側面131の表面積を調整することで、該漏電インダクタンスの大きさを改変可能である。すなわち、該長さ1311のサイズが該隔離槽113のサイズより小さければ該鉄芯体13と該積載板体121は間隙を形成し、さらに該高さ1312のサイズを対応させ、その漏電インダクタンスを調整することができる。本考案の複合式コモンモードコイル1は該側面の表面積を調整するだけで、該漏電インダクタンスの大きさを改変可能で、体積と製造コストの減少を達成することができる。   When a current flows through each of the plurality of coils 1234 in the coil rack 123, a leakage inductance is formed between the two coil racks 123. Therefore, the magnitude of the leakage inductance can be modified by adjusting the surface area of the side surface 131. That is, if the size of the length 1311 is smaller than the size of the isolation tank 113, the iron core body 13 and the loading plate body 121 form a gap, and the size of the height 1312 is made to correspond to the leakage inductance. Can be adjusted. The composite common mode coil 1 of the present invention can change the magnitude of the leakage inductance only by adjusting the surface area of the side surface, and can achieve a reduction in volume and manufacturing cost.

上記のように、本考案の複合式コモンモードコイルは公知技術の欠点を確実に克服可能で、産業界のニーズに応えることができ、産業競争力を高めることができる。   As described above, the composite common mode coil of the present invention can surely overcome the drawbacks of the known technology, meet the needs of the industry, and increase the industrial competitiveness.
