This is a voltage waterfall/ cascade that uses capacitors and diodes to "trap" the voltage and adding to it in the capacitor. The maximum voltage would be regulated by the capacitor max voltage, but since this simulator doesnt have voltage limits on the capacitor we just let it run. The final voltage can get into the kilavolts fairly quickly if the capacitor farads are increased. This example is only using 20 nano farads capacitors. Examples of use would be tazers, defibulators, electric fence circuits. Take notice to how each section boosts the amplitude a specific amount.
