Abstract
Excess DC current generated by a fuel cell stack may be provided to a current source inverter, and an AC current may be output by the current source inverter to a grid side bus. The AC current on the grid side bus may be used to support a load demand on a microgrid side bus or provided to a power grid. Various transmission buses and electric conditioning and control devices, such as rectifiers, current source inverters, motors, generators, electric contactors, relays, and/or transfer switches may be configured to use the AC current on the grid side bus to provide an AC current to the microgrid side bus to support the load demand on a microgrid side bus.
