Voltage Cuadriplicaodor Pico (1) (1)

This circuit shows the principle of voltage multiplier. It has been invented by Heinrich Greinacher (https://en.wikipedia.org/wiki/Voltage_multiplier). This works by sequently charging capacitirs, which in turn will charge following capacitors with a higher voltage. Each stage (capcitor + 2 diodes) doubles the peak input voltage.
