The forward converter of Fig. 7-5a has parameters Vs=170 V,N1/N2=10, N1/N3=1,Lm=340μH,Lx=20μH,R=10Ω,C=10μF,D=0.3, and the switching frequency is 500kHz. (a) Determine the output voltage and output voltage ripple. (b) Sketch the currents in Lx,Lm, each transformer winding, and Vs (c) Determine the power returned to the source by the tertiary (third) transformer winding from the recovered stored energy in Lm :
