Power system for data center

摘要

A power system (200) for data center (210), which comprises: a critical electrical equipment (211), an alternating current (AC) transformer (121), an AC power distribution unit (PDU) (123), a rectifier transformer (231), and a DC PDU (233). The critical electrical equipment (211) is disposed in the data center (210). The AC transformer (121) is utilized to receive a first high AC electrical power from a first power utility (120) and transform it to a low AC electrical power, and the AC PDU (123) receives the low AC electrical power and applies the low AC electrical power to the critical electrical equipment (211) of the data center (210). Further, the rectifier transformer (231) is utilized to receive a second high AC electrical power from a second power utility (130) and transform and rectify it to a low direct current (DC) electrical power, and a DC PDU (233) receives the low DC electrical power and applies the low DC electrical power to the critical electrical equipment (211).
