ELECTRONIC APPARATUS
Document Type and Number:
Japanese Patent JP2022181530
Kind Code:
A
Abstract:
To efficiently reduce both conduction noise and radiation noise with a small number of noise countermeasure components.SOLUTION: An image forming apparatus 100 comprises: an AC/DC converter 101; an AC filter 102; a ferrite core 110; two conductive parts 201; and a conductive part 202. The AC/DC converter 101 has two AC input terminals 121, 122, and a ground terminal 125. The AC filter 102 has two power terminals 131, 132 that are electrically connected with the two AC input terminals 121, 122 through the two conductive parts 201, two power terminals 133, 134 that are electrically connected with a live line 151 and a neutral line 152 of an AC cable 109, and a ground terminal 135. The conductive part 202 is electrically connected with a ground line 153 of the AC cable 109, the ground terminal 125, and the ground terminal 135. The two conductive parts 201 and the conductive part 202 pass through the ferrite core 110.SELECTED DRAWING: Figure 2
