Hello All,
I have a homework question that is actually related to the following threads (some were never answered, alas):
https://forum.allaboutcircuits.com/threads/buckboostconvertermosfetvoltage.161847/
https://forum.allaboutcircuits.com/threads/buckboostconverter.152091/
This homework is from the same course, and I need some guidance. The following questions are related, or I think related to one another.
The circuit in question:
The questions in question:
Per my attached work, I have derived the answer to #3 and it is correct.
I derived the answer to #6, but as a function of V, not Vg per the question. Shouldn't I be able to simply substitute the expression of V which is a function of Vg from #3 into #6? I cannot get the answer. So either my derivation of #6 is wrong, or I can't do algebra!
Guidance will greatly be appreciated.
