  • Apparatus and methods for providing robust powering
    Patent number: 5881215
    Abstract: A power system and method utilizes two independent AC lines to power an N+1 power supply configuration. The AC lines are selectively switched to supply power to the N+1 power supply configuration in response to power failure on one of the AC lines. The distribution system takes advantage of the N+1 configuration by always powering at least N power supplies. Sequencing of the switching is also monitored for incorrect power switching. Upon detection of incorrect power switching relays are forced open.
