Abstract
The utility model relates to an improved annular inductor, comprising an annular magnetic core and coils wound on the annular magnetic core. The improved annular inductor is characterized by further comprising a plurality of magnetic column blocks; two groups of the coils are arranged; and the coils are symmetrical to an axis of an annular plane, and are respectively arranged on a half ring of the annular magnetic core. The spiral directions of the two groups of coils are opposite; one or more magnetic column blocks are connected in series with the end parts of the coils; and epoxy resin is coated outside the magnetic column blocks. The improved annular inductor provided by the utility model has a simple structure and a withstand voltage value is improved. The high-frequency impedance of the annular inductor is improved by using a high-frequency impedance property of the magnetic column blocks through the magnetic column blocks at the end parts of the coils of the annular inductor.
