I see a bit of similarity between the flyback and boost converter. The
difference is that during the collapse of the magnetic field, the output
of a boost converter is pulled from the "bottom" of the "primary" (and
only) winding, while in a flyback converter, the output is pulled from the
"bottom" of the secondary winding. In the boost converter, the converter
output is in series with the incoming DC supply (boosting the voltage). In
a flyback converter, the output is generally ground referenced and
isolated from the primary.

So... I see similarities, but sometimes I see stuf that isn't there.
