Abstract

A power system for data center, which comprises: a critical electrical equipment, an alternating current (AC) transformer, an AC power distribution unit (PDU), a rectifier transformer, and a DC PDU. The critical electrical equipment is disposed in the data center. The AC transformer is utilized to receive a first high AC electrical power from a first power utility and transform it to a low AC electrical power, and the AC PDU receives the low AC electrical power and applies the low AC electrical power to the critical electrical equipment of the data center. Further, the rectifier transformer is utilized to receive a second high AC electrical power from a second power utility and transform and rectify it to a low direct current (DC) electrical power, and a DC PDU receives the low DC electrical power and applies the low DC electrical power to the critical electrical equipment.

Dependent claims

A power system for a data center, comprising:

a first critical electrical equipment disposed in the data center, and said first critical electrical equipment includes a first power supply unit with a first input port and a second input port;
an alternating current (AC) transformer for receiving a first high AC electrical power from a first utility power and transforming the first high AC electrical power to a first low AC electrical power;
a first AC power distribution unit (PDU) connected to said AC transformer for receiving the first low AC electrical power, and connected to the first input port for applying the first low AC electrical power to said first critical electrical equipment of the data center;
a rectifier transformer for receiving a second high AC electrical power from a second utility power, and transforming and rectifying the second high AC electrical power to a low direct current (DC) electrical power;
and
a DC PDU connected to said rectifier transformer for receiving the low DC electrical power, and connected to the second input port for applying the low DC electrical power to said first critical electrical equipment of the data center.
