Diode voltage doubler circuit given in figure bellow.
Simulate full wave diode doubler circuit.

diode-voltage-doubler

Diode voltage doubler i.e. voltage doubler rectifier operates as follows: during positive half period of the input sine voltage, diode D1 is forward biased, while diode D2 is blocked. Capacitor C1 is charging, and current path is given bellow.

diode_vol_doub_sch02

During negative half period of the input signal, diode D1 is blocked, while diode D2 is forward biased. Capacitor C2 is charging (current path is given bellow)

diode_vol_doub_sch03

By this way, each of the capacitors keeps polarity of VIN(MAX), so output voltage is twice VIN(MAX).
