FUEL CELL SYSTEM RIDE-THROUGH OF ELECTRIC GRID DISTURBANCES

摘要

A fuel cell system includes a fuel cell assembly configured to generate a direct current (DC) signal. The fuel cell system also includes one or more inverters coupled to the fuel cell assembly by way of one or more first bus lines. The fuel cell system also includes a variable frequency drive (VFD) coupled to an output of the one or more inverters and configured to receive AC power from the one or more inverters. The VFD is configured to convert the AC power to DC power and to provide the DC power to at least one auxiliary component during a normal operating condition. The fuel cell system further includes one or more second bus lines configured to receive the DC signal via the one or more first bus lines and to provide the DC signal to the VFD to power the at least one auxiliary component during a low voltage ride through condition.
