Claims

[Scope of utility model registration request]

In a magnetic core for a nonlinear chiyoke coil in which the direct current superimposed current and the inductance of the winding are nonlinear characteristics, which is constructed by combining an E-type core and an I-type core and winding the center leg of the E-type core, the core is opposed to the center leg of the E-type core. A magnetic core for a nonlinear chiyoke coil, characterized in that it has a structure in which a gap and a narrow magnetic circuit are provided on the surface of the I-shaped core.
