Homework Help: DC-DC Converter (Switching Converter)

  1. Oct 17, 2012 #1
    1. The problem statement, all variables and given/known data

    See figure below.


    2. Relevant equations

    3. The attempt at a solution

    See the 3 other figures attached for my attempt at the solution. (Parts (a), (b) & (c))

    Does anyone spot any mistakes in my work?

    I didn't go over your work in detail, but I see where you are naming this converter as a buck-boost converter. While it could be used as such, I'm thinking that the way the switches are synchronized would simplify it to a different topology (I could be wrong, though). Do you see what I'm referring to...? The switches are not normally synched to be closed at the same time and open at the same time in a buck-boost regulator, I believe...

    We've only learnt about 3 types of DC-DC converters in the course,

    1. Buck
    2. Boost
    3. Buck-Boost

    So I'm positive it would be one of those 3, and in this case it should be Buck-Boost I believe.

    Bump, still looking for someone to verify my work!
