Let's say that I'm using a DC boost-converter to control the speed of a motor like so:

Naturally, as the motor speeds up to higher RPM's there is an induced EMF that reduces the supplied current to the motor(due to the decrease in applied voltage). How can the back-EMF reduce the applied voltage (##V_o##) when it's parallel to the capacitor? That capacitor is just troubling my analysis... hence my confusion and the effects of series/parallel components.

I know for sure that this formula is true: ##V_o - V_e## = ##V_l## , but how with respect to the capacitor being parallel...

Where ##V_l## is voltage at load.
