Voltage Multipliers. Use either a Full-wave or Half-Wave rectifier circuit that outputs a DC voltage that is four times the peak voltage of the input AC voltage. Any size voltage multiplier may be produced by cascading the circuits shown below together.
The capacitors need to be sized to handle the maximum voltage. The input capacitors should be rated at least 30 percent higher than the required voltage, per standard Capacitor Derating Guidelines.

 Voltage Doubler. A rectifier circuit that outputs a DC voltage that is twice the peak voltage of the input AC voltage. The voltage doubler circuit rectifies each half cycle of the AC input voltage and combines the recified voltages using the capacitor to produce twice the peak amplitude of the input AC voltage. Voltage Doubler

Voltage Tripler. A Half-Wave Voltage Tripler uses three diodes to produce a DC output that is three times the peak AC input. The voltage rating of capacitor C1 should be rated at the input AC voltage, and the voltage ratings of capacitors C2 and C3 should be twice the AC voltage. Half-Wave Voltage Tripler

Voltage Quadrupler. A Full-Wave Voltage Quadrupler uses four diodes. Capacitor C1 and C2 should be rated at the input AC voltage, and the voltage ratings of capacitors C3 and C4 should be twice the AC voltage. Full-Wave Voltage Quadrupler

A common method to show voltage multipliers is to place the diodes at an angle on the schematic, however some engineering departments may not allow this particular configuration. Half-Wave Voltage Quadrupler

 High-Order Voltage Multiplier; Voltage multipliers may be produced by cascading the diode circuits together. There is no limit to the size of a voltage multiplier. The voltage ratings of the input capacitors should be rated at the input voltage [AC], while all the other capacitors should be sized at twice the input voltage [2x AC] regardless of the size of the multiplier. Each of the diodes should be rated at twice the AC voltage. Full-Wave Voltage Quadrupler
