  • Control systems and methods for minimizing power loss associated with fuel cell systems
    Patent number: 12027856
    Abstract: Embodiments of the present disclosure provide control systems and methods to reduce wastage of energy associated with fuel cell systems. The method includes transmitting DC power from a plurality of fuel cells of a set of power modules to a centralized DC bus through a first set of DC-DC converters. The method includes operating a second set of DC-DC converters to provide an output DC power by boosting a voltage level of the DC power from the centralized DC bus and further operating a first set of DC-AC inverters to convert the DC power from the second set of DC-DC converters to AC power. The method includes transmitting the AC power from the first set of DC-AC inverters to a grid. The AC power is transmitted to the grid at substantially unity power factor due to combined effect of switching modulation and MPPT of the first set of DC-AC inverters.
