Data center power network with multiple redundancies

Abstract:

Several embodiments include a power network system for a data center. The power network system can provide high voltage direct current (HVDC) power to server racks or any IT load racks type. For example, a HVDC converter circuit can provide the HVDC power by converting AC power. The power network system can also include multiple redundant power systems (e.g., a genset, a capacitive backup power system, a turbine-based generator system, or any combination thereof). The capacitive backup power system can provide HVDC power when the AC power fails and/or when the HVDC converter circuit can no longer provide sufficient power. The genset can be turned ON after the AC power fails. However, the genset may not provide stable power until sometime thereafter. Hence, the air turbine-based generator system can provide nearly-instant backup power once turned ON and provide supplemental energy in combination with the capacitive backup power system to smooth out transitions of power sources.
