Voltage Doublers
For ideal diodes, C1 charges to Vm through D1 when the source is positive; C2 charges to Vm through D2 when the source is negative. The voltage across the load resistor is the sum of the capacitor voltages 2Vm.
Voltage doubler circuits avoid using a transformer to step up the voltage, saving expense, volume, and weight.

Capacitor C1 charges to Vm through D1 when the source is positive, and C2
charges to Vm through D4 when the source is negative.
The output voltage is then 2Vm.
Diodes D2 and D3 remain reverse-biased in this mode.
