If you believe that di/dt remains constant while changing Ls, then
why not make Ls as large as possible?
Regarding Vs, I believe that if one applies Occam's Razor to the
problem, a simple equation ultimately determines the output voltage:
Energy in Csec = (energy in Cpri) X (coil efficiency)
The _only_ assumption that this equation relies upon is that energy
is always conserved. Given that E = 1/2 CV^2, the output voltage
immediately follows from this equation.
