[其它]Different mode conducted EMI of three-phase SCR rectifier: prediction and reduction

Abstract: This paper analyzed the EM1 that generated qLB(Th\&'  
from a Three-phase SCR Rectifier and some common "eI">`!g  
redaction measure effect.  According to the switching `2'*E\   
function, the noise equivalent circuit is obtained. Based on Y1BxRd?D  
these equivalent circuits, the noise spectrum calculation RC!T1o~L  
can be performed in frequency-domain. The experiment P[e#j  
results show the validity of the calculation, Since the /|<0,ozoJ  
calculation is in the frequency-domain, it doesn't need v^ 1x}
