Apparatus for providing high quality power
First Claim
1. A system, comprising:
- a power feed that distributes a high DC voltage in a building, wherein said high DC voltage is in a range of about 300 to 600 VDC;
a converter, coupled to said power feed, that receives said high DC voltage, and scales said high DC voltage to a low DC voltage; and
a controller that controls a firing rate of said converter so that said low DC voltage is in a range of about 23 to 48 VDC.

Abstract
The system disclosed herein is primarily utilized in the 23–48 volt DC telco, data center and industrial production industry. It will effectively replace today'"'"'s requirement of purchasing, installing, maintaining and replacing chemical storage batteries. The solution will be capable of deployment partially and in full, inside the building, outside of the building in environmentally enclosed containers or in a mobile version. Additionally, the distribution voltage application will allow for reduction in the size of the power distribution wiring as well as creating an environment that requires less cooling of the critical equipment. This effectively leads to less infrastructure space and equipment, i.e. UPS, air conditioning units, static switch units, generators and chillers, for the same amount of processing, and significantly increases overall system reliability. The system regulates AC power and produces DC power that is considered uninterruptible and that is high quality in nature.
