Abstract
Exemplary embodiments adapted to distribute power from four input lines to a plurality of power supply units (PSUs) configured in an N+1 architecture are provided. In one such embodiment, a plurality of rectifier devices have first and second ends, each of the plurality of rectifier devices connected at the first end to one of the four input lines, and adapted to be bypassed by a first relay in a first operating mode and provide rectified input current in a second operating mode. A plurality of second relays is connected between each of the second ends of the plurality of rectifier devices. The plurality of second relays are adapted to be closed in the second operating mode to sum the rectified input current from each of the plurality of rectifier devices in a single node connecting each of the plurality of PSUs.
