The internet and the demand for online connectivity are fuelling the energy consumption in Data Centers. According to DataCenterDynamics 2012 Global Census, the power requirements grew by 63% globally to 38GW, up from 24GW in 2011. The census estimated a further rise of 17% to 43GW in 2013. It is important that this growing demand for energy is met by the power supply from renewable energy sources. The Power SupplyDistribution System for FutureData Centers is shifting towards DC Architecture from existingAC architecture. In this paper, 380V DCis considered as the transmission voltage and 48 V DCas the distribution voltage inside the Data Centers. An efficient 380V to 48V DC-DC buck converter withless switching and thermal losses can reduce the cooling requirements of the Data Center. In this directiona suitableconfiguration is selected by comparingTwo- Stage, Half- Bridge, Push-Pull and Full-Bridge buck converters based on efficiency and power loss analysis.
