Patent ID: 8836164

Claim:
A polyphase power management system, comprising: a switching unit having a polyphase mains input with a neutral, a backup power input, a rectifier output and an other loads output; a mains monitor/controller coupled to said switching unit and configured to monitor said polyphase mains input and route: at least one nominal phase of said polyphase mains input to said rectifier output and another nominal phase of said polyphase mains input to said other loads output when at least three phases are nominal at said polyphase mains input, one nominal phase of said polyphase mains input to said rectifier output and another nominal phase of said polyphase mains input to said other loads output when only two phases are nominal at said polyphase mains input, one nominal phase of said polyphase mains input to both said rectifier output and said other loads output when only one phase is nominal at said polyphase mains input, and said backup power input to both said rectifier output and said other loads output when no phases are nominal at said polyphase mains input.
