Recently, the Chengdu Supercomputing Center, located in the core area of Luxi Intelligent Valley in Chengdu Science City with a total investment of about 2.5 billion NT dollars and a total construction area of about 60,000 square meters, was officially opened and inaugurated. Honored as the "most powerful brain" in western China, this supercomputing center aims to be the first in western China and will actively strive to be included in the system for the national supercomputing center. Delta provided 48 sets of HVP-336V/37A series high-voltage DC power supply systems for this supercomputing center, including AC power distribution units, rectifier units, DC power distribution units, and system monitoring units to provide reliable assurance for power.

As an ultra-large-scale and high-density data center, the Chengdu Supercomputing Center demands higher reliability, lower energy consumption, and lower investment when planning the power supply and distribution system, so it chose the high-voltage DC power supply system that enjoys more advantages in energy efficiency and costs of operation and maintenance. Compared with UPS AC power supply, the high-voltage DC power supply solution offers three obvious advantages:
1.The system offers high efficiency, with the high-voltage DC power supply used to directly supply power to the IT equipment in the data center. Under the condition of the same load, the energy efficiency can usually reach up to over 10%.
2.With a performance management feature that controls the sleeping of the rectifier module, the load rate of the rectifier module can be increased by making some of the rectifier modules sleep when the system load rate is low so that it works under the state of highest efficiency.
3.Since there is no requirement for synchronization of potential, frequency, phase, etc. for AC power supply, expansion of capacity with machines in parallel is also simpler.

The Delta HVP Series 240V high-voltage DC power supply system favored by the Chengdu Supercomputing Center has been successfully applied to many large-scale and ultra-large-scale IDCs such as the three major operators and large Internet companies, with the excellent performance in energy efficiency having been highly recognized by customers.

In addition, Delta's high-voltage DC system is more outstanding in its solution-oriented capabilities and can provide a complete set of end-to-end solutions according to different scenarios, so that customers can truly enjoy a one-stop service that helps reduce costs in management and operation while achieving high reliability, thus making it trusted by large IDC service providers.
