Title:
ELECTRIC APPARATUS UNIT
Document Type and Number:
Japanese Patent JP2023154654
Kind Code:
A
Abstract:
To provide an electric apparatus unit comprising a noise filter with high impedance.SOLUTION: An electric apparatus unit includes a housing which accommodates a noise filter for suppressing noise generated in a power converter. The electric apparatus unit comprises a conductive member and an insulator layer. The conductive member is arranged in the housing to connect the input terminal of the electric apparatus unit to the power converter. The insulator layer is interposed between the conductive member and the housing. An area S represents an area of the conductive member, an opposite part to the housing through the insulator layer. A distance d represents a distance between the opposite part and the housing. A dielectric constant ε represents a dielectric constant of the insulator layer. The area S, the distance d, and the dielectric constant ε are decided so that a capacitor generated by a configuration of the conductive member, the housing, and the insulator layer has an electrostatic capacitance of less than 1 nanofarad.SELECTED DRAWING: Figure 1
