Fuel cells as a backup energy source for high availability network servers
Abstract
This thesis proposes an uninterruptible power supply, UPS for high availability
servers with fuel cells as its back up energy source. The system comprises a DC to DC
converter designed to accommodate the fuel cellâ s wide output voltage range. A server
power supply is specified, designed and simulated for use with this UPS. The UPS
interfaces internal to the server power supply, instead of providing standard AC power.
This topology affords enhanced protection from faults and increases overall efficiency of
the system by removing power conversions. The UPS is simulated with the designed
power supply to demonstrate its effectiveness.
