Embodiment Construction

[0012] Such as Figure 1-2 As shown, the multi-purpose double-hole conjoined magnetic core is a split-combined double-hole conjoined magnetic core. Two "3"-shaped magnetic cores 1 are relatively assembled to form a whole "8"-shaped closed special-shaped magnetic core. Its cross section is substantially rectangular. The two "3" middle columns protrude in the form of right-angled vertical columns, which is convenient for winding the coil bobbin.

[0013] There may be air gap or no air gap at the closing part 2 of the two "3" middle columns, and it can be made of various soft magnetic materials, such as commonly used manganese zinc or nickel zinc ferrite, permalloy or silicon steel sheet, etc. The two "3" are completely symmetrical, forming a completely closed magnetic circuit. The circular transition is shorter than the E-shaped magnetic circuit and saves material. The transformer made of the frame covered with the center column and the electromagnetic induction coil wound on...

Abstract

A multi-purpose diplopore siamesed magnetic core is a diplopore siamesed whole '8'-shaped closed heteromorphic magnetic core which is formed by two '3'-shaped character patterns, namely two half-'8'-shaped character patterns; the column closure of the two '3'-shaped characters is provided with an air gap or not; and both sides thereof are completely symmetrical, thereby forming a completely closed magnetic circuit. The invention is characterized by having the advantages of simple assembly, easy electrical parameter adjustment, stable characteristics and good consistency. The invention improves the electromagnetic conversion efficiency on the condition of same cross-sectional area, leads the electromagnetic conversion efficiency to be over 96 percent, and simultaneously causes the working temperature of the magnetic core to be reduced to be below 135 DEG C. The invention reduces the length of the magnetic circuit, increases the area of the window, reduces the electromagnetic radiation and interference of the magnetic core when in work and lowers the cost.

Description

technical field [0001] The field of the electromagnetic coupling electromagnetic power conversion device of the present invention, especially the electromagnetic induction magnetic core of the transformer and the high frequency transformer, and is a multi-purpose double-hole conjoined magnetic core, mainly applicable to high frequency welding machines, electrostatic copiers, switching power supplies, etc. use. Background technique [0002] Existing high-frequency welding machines, electrostatic copiers, switching power supplies, etc. have large core loss, low electromagnetic conversion efficiency, high temperature rise, and large volume, which are not suitable for the current trend of energy saving and consumption reduction. [0003] The traditional EI-type and EE-type magnetic cores are the most commonly used shapes, and the electromagnetic conversion efficiency can only reach about 90% under a certain cross-sectional area of ​​the magnetic core. [0004] High-frequency we...
