I am making a large capacitor bank (I guess not that big, but enough to kill you a couple times over) and I need a little help with charging it. I am using 450 volt 1200uf electrolytic capacitors. I have them in two sub banks of 4 wired in parallel, and connected to each other in series. I only want to charge the bank to 800 volts (100 less than it is rated for) and am having a bit of trouble doing this on a budget.
I thought of making a ac transformer and then changing it to dc power, but I do not know of a way to create an acceptible circuit for ac to dc. I have tried to find the circuit diagram online but haven't really found anything.
Another solution I thought of was to create an DC/DC converter and up the voltage to the desired voltage through this. I did find plans for this on the internet, but they seem very complicated, and the problem is that they have it set for a certain output, in my case 10kv, way way too much. I don't know enough about the concept behind the circuit to limit it for my application.
Is there an easy way to limit DC voltage? Because if there is I could just use a neon sign transformer and go from there (those are dc output right?)
If anybody has any suggestions, please let me know, because I am going nuts.
Another thing I thought of was creating some sort of bleed valve for the capcacitors that would dissipate extra voltage when it got to a certain point. this way I could use anything above 800, and not really worry. Any ideas on how to do this?
