Missing - part. Of course, due to the increasing demand for humans, 'relatively, electronic devices must be used more functionally' to move electronic products toward the goal of diversification. With the increasing popularity of various electronic devices, television networks, switches, mobile devices, and office automation, the electromagnetic environment in electronic systems is becoming more and more complex, electromagnetic interference (EMI) is becoming more and more serious, and it becomes a scene. A clear obstacle to normal work. In the common common switching power supply, since the main £:]^1 interference source comes from the power action of the 7L piece of power, EMI dry mostly has common mode noise and differential mode noise. Eme (Electromagnetic Emission) is usually a broadband (four) news 'the frequency of the Fan Chen exchanges fresh to a few legs 2 . Please refer to Figure 1 for a schematic diagram of a transformer circuit with a common mode choke and a differential mode choke. The conventional transformer 2 receives an AC voltage source 2i and then outputs a DC voltage source 25 via a common mode choke 22 and a differential mode choke 23 to a rectifier 24. Because the common model 扼5 200926221 = «and county her _ 23 (secret ridiculous lion lion and poor _ news, but the known transformer 2 is due to _ big, production costs increase production, so how to solve 炷 _ The main object of the present invention is to provide a solution for the purpose of the invention. The main purpose of the present invention is to provide a "iron core" and a surface area of the side of the core. The adjustment can be performed to achieve the effect of the common mode coil changing the leakage inductance. The secondary purpose of the present invention is to provide a composite common mode, _, and the storage is replaced by a common mode design instead of the differential mode design. In order to achieve the above object, the present invention provides a composite common mode coil comprising: a base, a coil carrier and a core body. The base has a second housing. a slot and an isolating slot, the isolating slot is located between the two receiving slots. The coil carrier has a bobbin, the outer edge of the bobbin is wound with a plurality of coils, and the two bobbins are arranged correspondingly in the coil Placement In the slot, the core body has two corresponding sides, the core body is located in the isolation groove, and the side is adjacent to the bobbin. Wherein, the plurality of coils in each bobbin are respectively passed When a current is applied, the coil carrier is formed with a leakage inductance, and the size of the leakage inductance can be changed by adjusting the surface area of the side surface. In order to facilitate the other features and structures of the composite common mode coil of the present invention, it can be deeper. It is to be understood that the following is a detailed description of the embodiment of the present invention. The flow coil 22 (ch〇ke) and the differential mode 2323' have a large combined volume and are difficult to manufacture. The transformer 3 of the present invention receives the AC voltage source 31 and then passes through a composite common mode coil 32.

The carrier plate body 121 has a substantially rectangular three-dimensional structure, and the shape of the carrier plate body corresponds to the shape of the positioning groove 112. And the carrier body 121 is placed in the Guding trough. The body 122 is substantially cylindrical, and the field 122 is merged with the body 121, respectively. The wire _ one end 7 200926221 ring frame 1231, 1232 is formed in abutment, and the two half-coil frames 1231, 1232 are connected to form an accommodating space 1233, and the accommodating space 1233 is substantially shaped with the column 122. The shape is corresponding to a cylindrical shape, so the accommodating space 1233 can accommodate the column 122. The coil bobbin 123 is formed by abutting the two halves of the bobbin 1231 and 1232. A plurality of coils 1234 are wound around the outer edge of the bobbin 123, and the two bobbins 123 are disposed correspondingly in the receiving slots 111. The core body 13 is made of a rectangular solid structure ' and the core body η is made of a material having a high magnetic permeability. The core body 13 of the present invention has two corresponding side faces 131, and the surface area of the side face 131 is defined by a product of a length 1311 and a height 1312, and the direction of the height 1312 is substantially opposite to the direction in which the isolation groove 113 extends. Vertical. In the preferred embodiment of the present invention, the core body 13 is located in the isolation groove 113, and the side surface 131 abuts the coil frame 123. When a plurality of coils 1234 in each bobbin 123 pass a current, a leakage inductance is formed between the two bobbins 123. Therefore, the size of the leakage inductance can be changed by adjusting the surface area of the side surface 131. That is, the size of the length 1311 is smaller than the size of the isolation slot 113, so that the core body 13 and the carrier body 121 form a gap, and the leakage inductance can be adjusted according to the size of the height 1312. The composite common mode coil 1 of the invention only needs to adjust the surface area of the side surface 131 to change the size of the leakage inductance to achieve the effect of reducing volume and manufacturing cost.
