HALF WAVE VOLTAGE DOUBLER
A voltage multiplier, whose output d.c. voltage is double the peak a.c. input voltage, is called a voltage doubler below Figure shows the circuit, of a half-wave voltage doubler.
VOLTAGE TRIPLER
During the first positive half cycle, the capacitor C1 charges through diode D1 to a peak voltage Vm. During negative half cycle, capacitor C2 charges through diode D2 to twice the peak voltage 2Vm developed by the sum of the voltages across capacitor C1 and the input signal.
