Hello,
We are doing an Half Bridge LLC resonant converter with both internal & external leakage and magnetising inductance terms…(as in the attached diagram).
Please could you confirm the following three equations for this topology?
w0 = 1/ [L(res).Cr] (1)
where:
w0 = upper resonant frequency
L(res) = Lr + Llkp + Llkp//Lm
wp = 1/[L(mag).Cr] (2)
where:
wp = lower resonant frequency
L(mag) = Lm(ext) // (Llkp + Lm)
m ={ [Lm(ext)//(Llkp + Lm] + [Lr + Llkp +(Llkp//Lm)] } / {Lr + Llkp + (Llkp//Lm)}
(3)
This is derived with regard to AN-4151 by fairchildsemi…
