Can someone shed some light on how they went about solving this problem? I have been staring at this for a while now and am stuck after doing the normal equations that were taught during the lectures. Any pointers would be greatly appreciated. Thanks.

I'm still working on HW 5 myself and using the grace period. After doing Volt-Second balance and cap charge balance for the 3 intervals I calculated the average inductor current by finding the peak inductor current and setting the average inductor current equal to V/R. Combining these equations allowed me to eliminate D2 and to find M in terms of k and D1. After that I solved for k and pulled out f. Were you able to do problem 5.4c without getting into real nasty algebra with the quadratic equation while trying to find V/Vg?
I really didn't use the quadratic equation, but I don't know if I did it right. You can email me if you want talk about scortinas@gmail.com
I got the equations that you mentioned (thanks), but how did you solve for D1? I just can't see it.
