摘要
通过理论与仿真分析比较了相同尺寸下UUI新型结构磁芯和传统EE结构磁芯电感器的主要电气参数,如感量、磁通密度分布以及直流叠加特性,结果表明UUI电感器较EE型具有感量大、磁芯磁通密度分布更均匀、直流叠加特性较好的优点。
The main electrical parameters of UUI inductor with traditional EE structure magnetic cores in the same size were compared through the theoretical and simulation analysis, such as the value of inductor, magnetic flux density distribution and dc superimposed characteristics. The results show that UUI inductor has larger inductance, more even magnetic flux density and better dc superimposed characteristics.
