Research on Background Noise Test Method of EV-Chamber

In recent years, with the development of the new four modernization of automobiles, the function of the automotive electromagnetic compatibility anechoic chamber has also undergone great changes, such as the EMC anechoic chamber of new energy high-voltage components needs to introduce the transmission system and high-voltage power supply system into the traditional anechoic chamber. However, for this project, there is currently no perfect way to verify that the background noise meets the test requirements of at least 6 dB below the standard limit. This paper introduces an EVChamber background noise test method for electromagnetic compatibility, which is used for EV-Chamber background noise verification, and provides a new idea and method for the industry to improve background noise testing.
