The forward converter of Fig. 7-5a has parameters Vs=100 V,N1/N2=N1/N3=1, Lm=1mH,Lx=70μH,R=20Ω,C=33μF, and D=0.35, and the switching frequency is 150kHz. Determine (a) the output voltage and output voltage ripple; (b) the average, maximum, and minimum values of the current in Lx;(c) the peak current in Lm in the transformer model; and (d) the peak current in the switch and the physical transformer primary.
