A transformer includes a bobbin, an I-bar, the first U-core, and the second U-core. The bobbin in a tube shape is wrapped around by a number of windings of copper coil. An I-bar made of high permeable alloy has a first end and a second end. The I-bar is inserted into the bobbin and the first end and the second end of the I-bar protrude outside the tube of the bobbin respectively. A first U-core made of high permeable alloy is placed on one side of the bobbin and a second U-core made of high permeable alloy is placed on the other side of the bobbin. The two ends of the first U-core and the second U-core connect the I-bar through the films and the sunken parts of the first U-core and the second U-core are in opposition to each other.
