Abstract:
This paper describes a solution to a problem that occurs in the operation of data centers due to the disparity between the capacity of power supply equipment and the power consumption of information and communication technology (ICT) equipment. As a result of this disparity, the power supply modules and power supply units (PSUs) operate at a low load factor, which causes them to operate at low efficiency. Here we describe the operation of a supply management scheme depending on load factor for controlling the number of operating power supply modules in real time with a 380 V direct current distribution system and assess the performance of this scheme.
