Paul,
Notice the circuit has no capacitor and no inductor. There's no energy storage capability in that circuit.
A boost converter stores energy in the inductor in one part of it's operating cycle, then dumps that energy to the capacitor in the second stage. I've never seen an inductorless or capacitorless boost converter.
I doubt an oversimplification to that level is going to provide much usable information. The waveforms are completely different from how a real boost converter works.
