Abstract: The need for backup diesel generators in a data center is obviated by using fuel cells to convert a fuel to electrical energy, which provide backup power to equipment in a data center, which may include the servers in the data center and other important systems that normally use utility power. When the utility power fails, the equipment switches to backup power that is provided by fuel cells supplied with fuel (such as natural gas), possibly using a source of temporary power (e.g., a UPS or direct tie-in of batteries) while the fuel cells come online. The fuel may also be used to power a turbine or generator, coupled to a chiller for providing a cooled liquid to a cooling system.

Abstract: A power supply circuit includes a connector, a first power supply module, and a second power supply module. The first power supply module is connected to, and supplies power to, the connector. The second power supply module is connected to the connector and the first power supply module. The first power supply module stops supplying power to the connector and outputs a control signal to the second power supply module when a current flowing through the first power supply module exceeds a certain limit. The second power supply module supplies power to the connector when the second power supply module receives the control signal.

Abstract: A branch circuit monitoring system (BCMS) for monitoring branch circuit currents in one or more electrical circuit panels is described. The system is comprised of a data center server, one or more panel processors, each with one or more collection devices, and one or more current sensors per collection device. The BCMS is designed to be installed entirely inside the panel without the need for a dedicated enclosure or power supply to facilitate ease of installation and low-cost. The BCMS also allows for future upgradability through standard software updates so that the system can be updated or patched easily. The BCMS data center server collects, aggregates, stores, and serves historical branch circuit current data from the panel processors to networked users via a web server to provide visualization of data such as tables, charts, and gauges. Finally, the BCMS interfaces to third-party software suites using industry-standard protocols such as Modbus® TCP and BACnet™ for integration with data center infrastructure management or building management system software.
