摘要:
A noise propagating to outside of a power conversion device is reduced. A power conversion device includes at least one external electrode, a switching element, a noise filter connected between at least one external electrode and switching element, at least one first wire to connect at least one external electrode and noise filter, a second wire to connect noise filter and switching element, and a magnetic filter attached to second wire. An attenuation characteristic A [dB] and an attenuation characteristic B [dB] satisfy a relationship of B
