Because of the proportional relationship between computing power and energy consumption, the data center is undoubtedly a “big energy consumer”. According to the statistics of the U.S. Department of Energy, the power consumption of data centers accounts for 2% of the national electricity consumption. Technically, energy consumption can be reduced by 40% by upgrading the power supply systems. For example, using APS SiC MOSFET and diode in the high voltage DC power supply system can simplify the power supply structure, improve the efficiency and reduce the number of heat sinks.
The growth of global computer server farms and Internet traffic leads to the accelerated consumption of global energy production by this infrastructure. Now, it is estimated that 500,000 data centers and 32 million personal servers around the world consume 1.5% of the world's electricity-about 300 TWh per year.
