EMI (electromagnetic interference) in power electronics
Dec 30th, 2014, 5:31am
 
Hello
I built a flyback ZCT circuit with pspice and I want to calculate the EMI spectrum via LISN network, I have applied LISN to my schematic too . I have some problem : 1) I'm not sure about my ZCT flyback design 2)I'm not sure about my extraction EMI from LISN because my result is not the same as I expected .
I'm newbie in power electronic ,please help me out .

General rule - modelling switching noise tends to be a waste of time.

Put a noise suppression strategy into your design and then build and test it.

Give this a read as a starting point:
