Title:
HARMONIC FILTER USING SEMI-MAGNETIC BOBBIN
Document Type and Number:
Japanese Patent JP2022033814
Kind Code:
A
Abstract:
To provide a core reactor containing a semi-magnetic bobbin and a semi-magnetic bobbin used in the core reactor.SOLUTION: A bobbin 300 includes a cylindrical semi-magnetic core 310, and two flat circular flanges 320 joined to the cylindrical semi-magnetic core 310. The semi-magnetic core 310 is made of a high temperature resistant non-magnetic material. The bobbin 300 also includes a center hole 330 and a plurality of flange holes 340.EFFECT: The semi-magnetic bobbin is used to provide a core reactor that withstands high temperature while avoiding eddy current effect, saves power without adversely affecting power quality, and captures a harmonic current.SELECTED DRAWING: Figure 3A
