I have made a 3 stage voltage multiplier. My input is from the outlet so 120 V ac. I measure my output from the first and last capacitors of the bottom row as shown in the image. The output I am getting is 120 V dc. From the equation Vout(dc) = Vin(ac)*sqrt(2)*number of stages. With this equation I should be getting around 500 V dc theoretically. I am not sure what is going on, anybody have any insight. Thank in advance.

Hello and welcome to Electronics Point :)

What are your component values? Especially, what is the capacitance of the capacitors?

I assume your input frequency is 60 Hz?

What kind of meter are you using to measure the output voltage?
