  • Among the production technologies of nonwoven fabrics, a needle punching technique has one of the long history aid holds still important place. At the present time, it is used not only for scrimming with woven or knitted fabrics and other nonwoven fabrics, but also for applying the special fibers blending nonwovens at the web forming process in ender to manufacture economical and high value added-Products such as home furnishing industrial and technical purpose.

  • In this paper, the coupled inductor with three branches in two interleaved converter are analyzed to effectively suppress the high frequency circulating current since the circulating current controller cannot mitigate the high frequency circulating current. As a result, the novel averaged model including the coupled inductor with zero sequence components is developed for reducing the low and high frequency circulating current simultaneously.
