Conductive EMI Noise Measurement for Switched Reluctance Drive

The component parts of the tested four-phase switched reluctance drive are described with the four-phase 8/6 structure double salient reluctance motor, the four-phase asymmetric bridge power converter and the 89C52 MCU digital controller. The conductive electromagnetic interference noise measurement equipment is described with the function of separated common-mode noise and differential-mode noise. The tested results of common-mode noise and differential-mode noise of the tested switched reluctance drive are presented. The tested results of frequency spectrum are given.
