Hello, I am having trouble with this part. I am completely following until finding the DC component of the fet voltage. Can you explain what you said here a little more and how it pertains to the average voltage across the mosfet?Have you figured this out yet?
Think about what the voltage across the inductor has to be when the switch is on and with the switch is off when the converter operates in CCM.
