Study on power electronic converter electromagnetic interference experiment method

Abstract

Effective measurement is the foundation for predicting and suppressing EMI. This article implements an effective EMI experimental method to conduct conducted EMI testing on high-power three-phase converter power cables. Detailed analysis and discussion are conducted on the experimental instruments, experimental layout, installation details, and other issues during the experimental setup process. The experimental method has improved the EMI testing technology of the converter and has a certain universality, which has practical significance for predicting and analyzing the conducted electromagnetic sensitivity of power electronic equipment.
