That would reassemble a line voltage doubler (I use them to operate 3ph equipment from a single phase supply).

And you don't need a full bridge, just two diodes on one phase with neutral being the center point and each diode charging a series capacitor.

I posted a improved version of that on #1407, along with the capacitor ripple waveform. Just remember that using diodes its not possible to regenerate back to the source (Battery)

Using the circuit on #1407 one could technically triple the output as well. Just add another capacitor/diode/IGBT
