Patent ID: 7974106

Claim:
An architecture for a fuel cell power conditioning system comprising: a first fuel cell segment arranged to have a positive terminal and a negative terminal; a first DC/DC converter, an input of which is connected to the positive terminal of the first fuel cell segment and the negative terminal of the first fuel cell segment; and a second DC/DC converter, an input of which is connected to the positive terminal of the first fuel cell segment and the negative terminal of the first fuel cell segment; a second fuel cell segment arranged to have a positive terminal and a negative terminal, wherein the positive terminal of the second fuel cell segment is electrically connect to the negative terminal of the first fuel cell segment; a third DC/DC converter, an input of which is connected to the positive terminal of the second fuel cell segment and the negative terminal of the second fuel cell segment; and a fourth DC/DC converter, an input of which is connected to the positive terminal of the second fuel cell segment and the negative terminal of the second fuel cell segment; wherein the positive output terminals of the first and third DC/DC converters are connected to a common positive voltage bus, wherein the negative output terminals of the second and fourth DC/DC converters are connected to a common negative voltage bus, and wherein the negative output terminals of the of the first and third DC/DC converters and the positive output terminals of the second and fourth DC/DC converters are connected to a neutral bus.
