Multi capacitor charge and discharge.

There's a much simpler way to do that by using just diodes, and a square wave signal. But if you really wanna know, ask hurz... he knows more than I do on that, he showed me how to do it too, and could probably tell you more than I could about it. But basically, it charges the cap during one cycle of the square wave signal, and then discharges it in series with the source as if it were another battery; thus doubling your source voltage with each stage. By using the diodes to replace the job that the relays are doing because they'll only conduct during the positive half of the square wave signal.
