4.1.4. Circuit Operation Theorem
4.1.4.1. EMI filter
EMI components have CM inductor,DM inductor,CX1,CX2,CY1, and CY2
1. CM inductor:To be used the High μFerrite core,and the inductance is
high (~mH or more 10mH)
2. DM inductor:To be used the low μ Iron poweder core ,and the inductance
is lower(10uH or more 100uH)
3. X capacitor :To be placed between L and N,and the capacitance is usually
0.1uF to 1uF
4. Y capacitor :To be placed L-G and N-G ,and we often pair the CY1,and
CY2 for EMI
