Hi, I have five 450v 680uf capacitors. I'm trying to charge them to around 400 volts. For increasing battery voltage I tried using a 12vdc to 220vac inverter. Then I connected the inverter's output to a full bridge rectifier that I made it myself and it gave me around 300vdc. Then I charged up one single 450v cap and It charged up to around 300 volts without any problem. The problem is that I have a circuit that has five of these big caps and the rest are some diodes, resistors and LEDs. All of these caps should charge at the same time. I connected the dc power to my circuit but it didn't work! The voltage at the beginning of the circuit was zero but the voltage that was coming out of the rectifier was around 300v. I thought that the problem is current. So I connected two resistors is series before the power reached the circuit. The resistors were 220ohms 20watts but it still didn't work. My inverter is 500 watts and My battery is 16v 5A(Of course I decreased the voltage before connecting it to the inverter). I also tried some of the ZVS dc-dc 390v boosters but I ended up frying them too. I don't have any idea. Maybe I can use a transformer? I don't know.
