Embodiment Construction
[0027] The present invention will be further explained below in conjunction with specific embodiments and accompanying drawings.
[0028] see Figure 1a-1d , the present invention comprises two magnetic cores with the same structure, the material of the magnetic cores is Mn-Zn ferrite, the magnetic cores comprise a magnetic core main yoke 3, and the two ends of the magnetic core main yoke 3 are symmetrically arranged with a left lateral yoke 1 and a right lateral yoke 2. The core main yoke 3 is provided with a magnetic core center post 4, and the magnetic core center post 4 is provided with a hole 5 passing through the magnetic core center post 4 and the magnetic core main yoke 3, and the two magnetic cores are along the core center post 4. The top surface is axially symmetrical butted, the two magnetic cores are fixedly connected by a skeleton, and the pores 5 of the two magnetic cores are connected, see Figure 4 , the inductance winding 7 passes through the aperture 5 and ...
