7.10 the forward converter of fig. 7-5a has parameters vs 100 v, n1/n2 5, n1/n3 1, lm 333 h, r 2.5 , c 10 f, and d 0.25, and the switching frequency is 375 khz. (a) determine the output voltage and output voltage ripple. (b) sketch the currents ilx, i1, i2, i3, ilm, and is. determine the power returned to the source by the tertiary (third) transformer winding from the recovery storage energy in lm.
