Claim 5:
6. The power converter of claim 1, wherein said at least two bi-directional power conversion circuit modules comprise:
an AC input connected to said AC port through said plurality of switches;
at least one high-voltage capacitor for storing power;
an inductor connected in series with said AC input,
a low-voltage capacitor,
two high-voltage switches connected between a first AC input terminal and opposed ends of said high-voltage capacitor,
two intermediate low-voltage power switches connected between said opposed end of said high-voltage capacitor and opposed ends of said low-voltage capacitor, and
two terminal low-voltage power switches connected between said opposed ends of said low-voltage capacitor and a second AC terminal,
wherein a DC load can be connected to said opposed ends of said high voltage capacitor;
a modulator receiving a reference signal from a converter controller;
a state selection circuit receiving said at least one comparison signal and outputting a state signal;
a switching pulse generator receiving said state signal and connected to gates of said power switches.
