  • Fuel cell based microgrid
    Patent number: 12438377
    Abstract: A system for fuel cell based microgrid is provided. The system includes a plurality of fuel cell modules to generate DC power. The system includes a plurality of dual-mode inverters (DMIs) to convert the DC power into AC power. The system includes a plurality of DC switches to electrically connect or disconnect a fuel cell module from a DC bus. The DC bus is electrically coupled to the plurality of the DC switches. The plurality of DMIs includes a first set of DMIs, second set of DMIs, and a third set of DMIs. The first set is configured to electrically connect a first set of fuel cell modules with a grid. The second set of DMIs is configured to electrically connect a second set of fuel cell modules with a first load. The third set of DMIs is configured to electrically connect the DC bus with the first load.
