Calulating power stage poles and zeros of full bridge converter?

If I have a full bridge converter with an output LC filter, then when I am calculating the power stage poles and zeros, I should refer the output inductor and the output capacitor to the primary side.

I presume that the referred impedance of the output inductor becomes L * (np/ns)^2?

Also that the referred output capacitor becomes C * (ns/np)^2?

..or do I have to calculate the entire LC impedance, and then refer that back to the primary as Z(LC) * (NP/NS)^2
…and then extricate the referred L and C values from that?
 

I analyse it by looking at the secondary as a buck converter with the input voltage transformed through the transformer turns ratio.

Thanks, of course, in that way, you must refer the primary side sense resistor through the transformer aswell?
 

Yes, you've got it.
