5. Calculate the resonant inductor value, Lr Lr = O.12V;nmin/fr~sIlXmlt ax= 176 nH 6. Calculate the resonant capacitor value, Cr Cr = .025/fr~s2IlXlmt ax= 90.9 nF 7. Calculate and check resonant impedance Zn Zn = (Lr/Cr)1/2 = 1.39 n (yes, < 1.5 ohms) The basic sections...
This demonstrates that the optimum capacitance (1 nF), causes a peak on the drain node lower than the AMR. To achieve the same snubber effect (similar Vdsmax), when RCD snubber is used, the snubber capacitance is maintained at 1 nF while it must be chosen an appropriate snubber resistance...
