Abstract

In this paper, we analyzed the effects of the ground connections on the CISPR25 conducted emission test. We verified that the conducted emission noise of remotely grounded EUT varies at the specific frequency band according to whether the housing ground is included or not. We also confirmed that similar variations are generated for an actual product sample at the CISPR25 radiated emission test. Consequently, the housing ground condition has to be more clearly defined at CISPR25 by considering the ground conditions of the components in the vehicle. In the foreseeable future, the effect of housing ground on radiated emission noise will be studied at the next paper in detail.
