Projects with EGND, Where do I stipulate in PI Expert?

Posted by: natb1 on 10/08/2019

Greetings,

I am designing a universal input open frame flyback.
Where do I tell PI Expert there is an EGND?
Mostly so it can help me design the EMI filter.

Thanks!

Since the AC input of the flyback circuit in PI Expert is two-port [line and neutral only], the EMI filter does not have a reference to earth ground. PI Expert does not support adding an earth ground to EMI filters for isolated flyback circuits.
