POWER CONVERSION DEVICE AND AIR CONDITIONER

WIPO Patent Application WO/2021/214831

A1

The purpose of the present invention is to reduce noise propagating to the exterior of a power conversion device.　A power conversion device comprises at least one external electrode (1-4), a switching element (6), a noise filter (5) connected between at least one external electrode (1-2) and the switching element (6), at least one first wiring (100-101) connecting at least one external electrode (1-2) and the noise filter (5), second wiring (103) connecting the noise filter (5) and the switching element (6), and a magnetic filter (7) attached to the second wiring (103). When the attenuation characteristics of the noise filter (5) are represented by A [dB], and the attenuation characteristics due to spatial coupling between at least one first wiring (100-101) and the second wiring (103) positioned between the switching element (6) and the magnetic filter (7) are represented by B [dB], the attenuation characteristics A and the attenuation characteristics B satisfy the relationship B
