1. An equipment operable to receive and operate on AC and DC input power, comprising:
- an AC distribution system which is operable to receive and distribute AC input power;
a DC distribution system which is operable to receive and distribute DC input power;
one or more AC/DC converters operable to receive AC input power from the AC distribution system and to produce one or more first DC outputs;
one or more DC/DC converters operable to receive DC input power from the DC distribution system and to produce one or more second DC outputs; and
an output combining element operable to couple at least one of the one or more first DC outputs and the one or more second DC outputs to a load.

Abstract
A multiple-input redundant power system accepts both AC and DC power inputs. Redundancy is further provided by the use of converters for the AC input, and converters for the DC input. An output distribution element provides for simple combining of converter outputs, and for more complex load sharing and load control arrangements. Advantages accruing from the AC/DC input approach are savings in facility infrastructure, since existing power sources can be utilized, and high availability and reliability in accordance with certain embodiments. The approach has many applications in computing and telecommunications.
