  • Patent number: 9742198
    Abstract: A redundant path power subsystem comprises a plurality of phase regulators in a multi-phase power converter. The plurality of phase regulators comprises at least N+2 phase regulators. N phases are sufficient to serve an electrical load coupled with the redundant path power subsystem. The redundant path power subsystem also comprises a plurality of power supplies, and a plurality of input and control paths between the plurality of power supplies and the plurality of phase regulators. The plurality of input and control paths comprises a plurality of multiplexing logic devices and a plurality of phase controllers. The plurality of phase controllers is configured to control the plurality of phase regulators. The plurality of multiplexing logic devices is configured to multiplex control signals from the plurality of power supplies and a microprocessor for the plurality of phase controllers.
