Data center is a global collaborative network of specific equipment, which is used to transfer, accelerate, display, calculate and store data information on the Internet infrastructure. Most of the electronic components in the data center are driven by low DC power supply. [1]

It will gradually become a part of modern social infrastructure like transportation and network communication, and then have a positive impact on many industries. However, the development of data center should not only rely on experience, but also really combine practice to promote the data center to play a real value role and promote the rapid change of society.
