摘要
将磁性元件绕组集成在多个磁芯组合的磁路上,称之为阵列式集成磁件。详细地分析了四磁芯结构阵列式两电感集成磁件的集成原理,分析了五种磁芯组合情况下两电感的耦合度大小,并作了有限元仿真分析验证。同时,将其中对角开气隙的磁件应用于两通道交错并联变换器。仿真分析和实验结果证明了理论分析的正确性和集成磁件的实用性。组合磁芯结构由于磁芯间气隙的存在,相对于传统整体磁芯降低了磁芯,的集中发热点,同时增加了磁芯的散热面积,降低了热损耗。阵列式磁芯的多磁路结构又为多绕组的集成提供了可能。
Magnetic component windings are integrated on several magnetic cores which are called array integrated magnetics. The integrated principle about four magnetic cores and two inductors array integrated magnetics is analyzed in detail as well as the coupling degree of two inductors in the case of five types association of magnetic core. The magnetics which have diagonal air -gap are applied in the two leads staggered-shunt converter. The simulation and the result of experiment present that the theory is correct and the integrated magnetics are practicability. Combined core compared with conventional whole core has lower heat, more radiating area and lower thermal losers because of the air-gap of magnetic core. Magnetic structure of array magnetic core enables winding integrated.
