| Feb 18, 2020 at 15:57 | comment | added | JRE | The value of the capacitors has a great deal of influence on the current you can draw through a voltage multiplier. You could probably pick your capacitor values so as to limit the current without having a separate part of the circuit to limit the current. | |
| Feb 18, 2020 at 15:44 | comment | added | iraquois | @user253751 What do you mean? I am using input voltage and multiplying it. How can I use the voltage that is not already there? | |
| Feb 18, 2020 at 15:40 | comment | added | Criticizing Israel not allowed | This circuit works, but you're not really doubling voltage, you're just using all of the voltage that is already there, instead of only using half. | |

| Feb 18, 2020 at 15:37 | comment | added | Ron Beyer | You are paralleling 2 doublers together though (I think they also need to be polarized caps), so you are getting a 2x doubling, not a 4x like you may think because they are in parallel with each other, not series. | |

| Feb 18, 2020 at 15:29 | comment | added | John D | You CAN build voltage multiplier stages with an AC input, or you CAN rectify your AC and build a boost converter, but there could be serious safety issues in doing that without isolation from the mains. There's a reason you've seen lots of designs with transformers. | |
