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

Abstract: This paper analyzed the EM1 that generated #)N}F/Od^  
from a Three-phase SCR Rectifier and some common xRM)f93@  
redaction measure effect.  According to the switching 1x~dsM;q  
function, the noise equivalent circuit is obtained. Based on 'l*p!=  
these equivalent circuits, the noise spectrum calculation ?B~S4:9  
can be performed in frequency-domain. The experiment gG6j>%y  
results show the validity of the calculation, Since the U0X?~ 1  
calculation is in the frequency-domain, it doesn't need 8%D 2G i  
many parasitical parameters and the calculation time can fC$(l@O?  
be greatl .. iSg^np
