The AC source acts as an independent voltage source, Yes, but the diodes can only pass current in one direction. If the input voltage to the rectifier is lower than the output voltage, then the ac source plus rectifier will no longer act like an independent voltage source, it will act like an open circuit.
In other words, the field is everywhere smaller, by the factor $1/kappa$, than in the case without the dielectric. Since the voltage difference is a line integral of the field, the voltage is reduced by this same factor. Since the charge on the electrodes of the capacitor has been taken the same in both cases, Eq.
