DC-BASED DATA CENTER POWER ARCHITECTURE
First Claim
1. A DC-based power distribution architecture for powering a data center, comprising:
- a first stage for delivering AC power to the data center from a utility line and from a distributed energy resource, wherein both the utility line and distributed energy resource provide AC power to a first node and second node;
a second stage that includes a first set of rectifier/charger (RC) units coupled to the first node that converts AC power to DC power and outputs the DC power to a first distributed bus bar, and a second set of RC units coupled to the second node that converts AC power to DC power and outputs the DC power to a second distributed bus bar;
a third stage that includes a first set of DC/DC converters that steps down the DC power from the first distributed bus bar to a first stepped down DC voltage, and a second set of DC/DC converters that steps down the DC power from the second distributed bus bar to a second stepped down DC voltage; and
a fourth stage that includes a dual path power distribution system that is powered by both the first stepped down DC voltage and the second stepped down DC voltage.
