摘要： A system and method of provided power to one or more electrical loads of an electrical load module is provided. The electrical load module includes an alternating current (AC) power input port, a direct current (DC) power input port, a power distribution device, a first power supply device, a second power supply device, and a first electrical load component. The power distribution device is electrically coupled to the AC power input port via a first connector and the DC power input port via a second connection. The first electrical load component is coupled to the first power supply device and the second power supply device. The first power supply device and the second power supply device are configured to provide power to the first electrical load component and a feed from an alternative power source system is directly connected to the DC power input port of the electrical load module.

摘要： A method of operating a power generation system, such as a fuel cell power generation system, includes providing a first electrical power up to a threshold amount of power to a load from at least one power module via a plurality of DC/DC converters and a DC power bus, determining whether electrical power from a utility is available, and providing a second electrical power from the at least one power module to a rectifier path via a plurality of DC/AC inverters in response to determining that the electrical power from the utility is available. The second electrical power includes electrical power generated by the at least one power module in excess of the threshold amount of electrical power.

摘要： Systems and methods include a power module comprising at least one fuel cell generator for powering a load, and a bypass mechanism having a first, normally-open fast-acting switch that closes in 1-250 msec, and a second, normally-open switch in parallel with the first switch, the bypass mechanism being electrically connected between the load and a second power source, such as a grid source, where the first switch is configured to close in response to a fault event such that when the first switch is closed power to the load is provided from the second power source through the first switch, and the second switch closes after a predetermined time such that power to the load from the second source is provided through the second switch. Additional methods and systems include providing power to a plurality of loads using fuel cell power generators.
