    so here's a simple voltage doubler, 2 diodes, 2 caps, should be a breeze, right? But I'm having a hard time understanding exactly how this circuit works, and I'd love if someone would just walk me through it, from time 0 through as far as you care. What really confuses me is the big current spike at about 10ms through D2... and yet the voltage on both the caps remains constant. Where is all this current going?

    Who say the voltage over the caps are constant?

    What is the voltage over C2?

    If you can find that, you're on the road to understanding.

    TOK ;)
