1. A voltage doubling power converter for converting a single-phase input signal to a three-phase power output signal, comprising:
a single-phase input having a Vin1 and a Vin2 and having a voltage differential Vin12;
a plurality of storage capacitors connected in series;
a plurality of switching modules, each of the plurality of switching modules having a pair of solid-state switching transistors, the plurality of switching module connected in parallel to the plurality of storage capacitors;
a controller activating the solid-state transistors to generate a three-phase output;
a three-phase power output having a Vout12, a Vout23, and a Vout31, each at about double Vin12, and 120 degrees out of phase with each other; and
wherein the plurality of switching modules charge the plurality of storage capacitors to about three times Vin12.
