ANS :-

Design the Interleaving DC/DC Converter

The parameters we have,

Vin = 50 V

Vout = 3 V

Iout = 100 A

fs = 20 KHz

from these we found,

D = Vout/Vin = 3/50 ==> D = 0.06

Po = Vout * Iout ==> P = 300 W

R = (Vout)^2/P ==> R = 0.03 ohms

IL1 = IL2 = Iout/2 = 50 A

we take 10% ripple in inductor current so,

deltaIo1 = deltaIo2 = 5 A

L1 = Vout*D/fs*delta(IL1) ==> L1 = 7.05*e-6 H

L2 = Vout*D/fs*delta(IL2) ==> L2 = 7.05*e-6 H

we take 5% ripple in output current so,

deltaVo = 0.15 V

C = (1-D)/8*L*(fs)^2*(deltaVo/Vo) ==> C = 0.416*e-3 F

Now we can make a simulation of interleaving forward converter as per all perameters
