Project 2

Interleaved converter :

Vin = 45-60V

V0 = 3V

I0 =100A

R = V/I = 0.03 ohm

fs = 50KHz

1. Duty ratio,

Vout/vin = D(N2/N1), D is considered as 0.5

N2/N1 =0.1

Inductor design

L = (Vout * 1-D/ fs* deltaIL) = 1uH

C = (1-D) / (8*L*fs^2*(deltaV0/V0)) = 0.25mH

The input voltage to the converter is 60 V and output voltage obtained is 3V.
