Abstract: A method of controlling an inverter having a three phase output and a plurality of single phase loads connected to respective one of the three phases of the three phase output includes determining if a first phase of the three phase output has a heavier load than a second phase of the three phase output, and providing a higher output power from the inverter to the first phase than to the second phase if it is determined that the first phase has a heavier load than the second phase.

Abstract: A method of operating a fuel cell system which includes a plurality of fuel cells and a plurality of auxiliary components located in at least one cabinet, includes monitoring, by a control unit, a parameter of the fuel cell system, determining whether the parameter has violated a threshold, and varying an auxiliary bus voltage provided to the plurality of auxiliary components connected to a common auxiliary bus by a first amount in response to determining that the parameter has violated the threshold.

Abstract: Systems, methods, and devices of the various embodiments enable parallel control of multiple uninterruptable power modules (“UPMs”) connecting multiple power sources to a bus in parallel. A UPM may be comprised of at least one controller coupled to at least one inverter, and the UPM may be configured to convert the DC voltage output from a DC source to an AC voltage, such as an AC voltage suitable for output to an AC bus. A UPM may receive a power sharing command and control its at least one inverter based at least in part on the received power sharing command to output a voltage to a bus.
