Voltage quadrupliers are used in Power supplies, increasing in alternating voltage and converting it into a continuous voltage (DC). The continuous voltage has a value corresponding to 4 timer the peak of the alternating voltage applied to the input. The circuit was simulated using 1N4001 diodes, but you’ll need 1N4004 or 1N4007 for practical applications.
