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
