So, I'm trying to load my caps with 12VDC -> 230VAC inverter and it works fine. It gives about 320V when I rectify the voltage.
But is there any rather easy way to rise the voltage to about 380V or even higher to 750V? I won't be breaking the inverter up, because I need it for other uses as well.
I have tried to build Villard voltage doubler to be used with the inverter, but with no luck. It gave out just 28V. (??)
Any hints would be welcome, as I'm a bit newbie with electronics.

Mmm.. I build Charge-Pump Voltage Doubler as instructed on the wiki. But it is obviously sucking too much juice, because my inverter switch off and blinks "overload" light. Putting a resistor between the inverter and voltage doubler does help, but the output is just a bit over 50V.

In some countries one of the wires is at ground level but in other countries both the wires have a voltage relative ground level. So if you ground one of them you might blow a fuse or something else that is not desirable.
Something strange is going on with your voltage doubler so you need to debug it to find out what.

Heh.. A new problem. The voltage double is working perfectly, it rises the voltage to 600V pretty fast.
So I thought "oh, what the heck, let's get it even higher!", and build a voltage tripler. It works nicely, loads it's own caps to over 900V, but when I'm trying to load my coil guns caps (2x450V 4700uF in series), it just doesn't work. The voltage stays at 4-7V.
I made the tripler several ways and they all "worked" alone, but not with those big caps.
So.. any pretty advices? You have been so helpful for so far.
