Control systems and methods for minimizing power loss associated with fuel cell systems

A system, comprising:

• a set of power modules, each power module of the set of power modules comprising a plurality of fuel cells configured to generate direct current (DC) power;
• a first set of direct current-to-direct current (DC-DC) converters comprising an input terminal and an output terminal, wherein each DC-DC converter of the first set of DC-DC converters is electrically connected to a corresponding power module of the set of power modules at the input terminal;
• a centralized DC bus formed by an interconnection of the output terminal of each of the first set of DC-DC converters;
• a second set of DC-DC converters electrically connected to the centralized DC bus, the second set of DC-DC converters configured to provide an output DC power by boosting a voltage level of the DC power received from the set of power modules through the first set of DC-DC converters and the centralized DC bus;
• a first set of direct current-to-alternating current (DC-AC) inverters comprising a DC end and an AC end, wherein the first set of DC-AC inverters is electrically connected to the second set of DC-DC converters at the DC end, and the AC end is electrically connected to a grid;
• and
• a control unit communicably coupled to the first set of DC-AC inverters and the grid, the control unit configured to at least:
• operate the first set of DC-AC inverters to convert the DC power output from the second set of DC-DC converters to AC power, and
• facilitate transmission of the AC power output of the first set of DC-AC inverters to the grid based at least on determining one or more parameters associated with the grid are within a threshold limit, wherein the first set of DC-AC inverters enables transmission of the AC power to the grid at substantially unity power factor.
