Hi,
I'm constructing a high voltage equipment to be used for electrostatic experiments. Thus I would like to have this source to be positive / negative and have the option to linearly control the output level.
I have managed to control the output linearly using a feature in a 20W power supply (6000V with 3.3mA max). With the intent of augmenting this output voltage through a voltage multiplier, I have created a stacked solid-state relay switching circuit in order to obtain a pulse train between 0V and 6kV at 30Hz. This switching also works correctly.
I have a problem with the voltage multiplier (I'm using ceramic 1nF capacitors and BY724 diodes). According to my simulations, the circuit should operate with double the input voltage but I am not getting a voltage increase. I'm also not obtaining the expecting rectification.
Could you please highlight any possible issues you can think of? I'm thinking that maybe I do not have enough current for the diodes - maybe I need to change the diodes with better ones?
Thanks for your replies!
