Title:
電気回路体及び冷凍サイクル装置
Document Type and Number:
Japanese Patent JP7394196
Kind Code:
B2
Abstract:
Provided are an electric circuit body and the like for properly suppressing noise. The electric circuit body (100) is provided with: a noise filter board (10) mounted with a noise filter circuit (11) and connected to an AC power supply (E); an inverter board (20) mounted with a power conversion circuit such as, for example, an inverter circuit (24) and having the input side connected to the noise filter board (10) via first wires (fa, fb, fc) and the output side connected to a motor (M) via second wires (gu, gv, gw); and a first ring core (30) around which the first wires (fa, fb, fc) are wound.
