The output voltage (the sum of voltages under C 2 and C 4) rises until 4U s is reached. In reality more cycles are required for C 4 to reach the full voltage. Each additional stage of two diodes and two capacitors increases the output voltage by twice the peak AC supply voltage. Voltage doubler ... Voltage Multipliers (Doublers, Triplers, Quadruplers, and ... Voltage Doubler. A voltage doubler application is a DC power supply capable of using either a 240 VAC or 120 VAC source. The supply uses a switch selected full wave bridge to produce about 300 VDC from a 240 VAC source. The 120 V position of the switch rewires the bridge as a doubler producing about 300 VDC from the 120 VAC. In both cases, 300 VDC is produced. This is the input to a switching regulator producing lower voltages for powering, say, a personal computer. Voltage Multipliers: Voltage Doubler, Tripler and Quadrupler If no load is conned to the output terminals the voltage will be twice the input peak voltage. In the case of load connected, the voltage level of the capacitor C1 will drop below the input peak voltage during the negative half and capacitor C2 level will drop during the positive half cycle.
