Above all, data centers produce enormous amounts of heat. Servers and cooling systems account for the greatest share of direct electricity use in data centers today. Typically, almost 50 percent of the electricity consumption related to data centers is due to cooling and uninterruptable power supply (UPS) demands.
The heat is removed by cooling equipment that also runs on electricity. To make cooling processes more efficient, Infineon offers all semiconductor technologies: Silicon (CoolMOSTM) and wide-bandgap semiconductors such as silicon carbide (CoolSIC™) and gallium nitride (CoolGaN™). These wide-bandgap technologies in particular have become a key lever to achieve more with less energy. They allow for greater power efficiency, smaller size, lighter weight and lower cost.
An example to illustrate these advantages: If every U.S. data center used the respective Infineon solution CoolGaN™, 4 billion kWh per year could be saved, which amounts to 2 million tons CO2 emissions less per year. CoolGaN™ devices are already being used to build highly efficient power converters for servers in data centers
