In one embodiment of the present invention, a bi-directional power converter is described. The converter comprises a first bi-directional DC-DC conversion device having a first plurality of bi-directional DC-DC converters, a plurality of power supply ports, each connected to at least one of the first plurality of bi-directional DC-DC converters, and a voltage medium capacitor, which is connected to each of the first plurality of bi-directional DC-DC converters and has a first voltage greater than a second voltage measured at each of the power supply ports. The converter further may comprise a third bi-directional DC-DC converter device, which is connected to the voltage medium capacitor and is connected to a voltage high capacitor. The converter also may comprise a bi-directional AC-DC conversion device, which bi-directional AC-DC conversion device is connected to the voltage high capacitor and at least one inductor, which is connected to a plurality of AC ports. In another embodiment of the present invention, at least one of the DC ports may be a hydrogen fuel cell. |
