Hai everybody,

Anybody tell me what are the disadvantages and advantages of full wave voltage doubler(capacitor and diode combination)?
 

The bridge (or Greinacher) type qualifies as a full wave voltage doubler. Also the Cockcroft-Walton type.

Full wave refers to the fact that the load capacitor receives a charge during both the positive and negative halves of the AC supply cycle. Hence this excludes the Villard doubler.

Full-wave has less ripple voltage than half-wave.

Full-wave requires more components than half-wave.

Some comparisons can be found at this link:

I have a Youtube video which is an animated simulation of the Greinacher voltage doubler. It portrays capacitors charging and discharging. It portrays current bundles moving through wires.
