并联型有源电力滤波器中磁集成技术的应用研究

Research on the Application of the Magnetics Integration Techniques in Shunt Active Power Filter

介绍了磁集成技术在并联型有源电力滤波器(SAPF)的应用思路。电感的解耦集成技术可以减小磁件体积,降低磁件损耗,提高系统的整体效率。针对不同的磁心材料进行了损耗对比分析。计算结果说明,磁集成技术在并联型电力有源滤波器中有一定的应用前景。

The concept of MI （Magnetics-integration） techniques used in shunt active powerfilter is introduced. The decoupied integrated-inductor is chosen, which can help to reduce the core size, core loss, and improve systems efficiency. Contrast analyze have be done with different core material. Analysis resuits indicate that SAPF with MI has advantages in the core loss and core size reduction, compared with the discrete inductor.
