摘要

With increasing component count inside the microprocessor, computer has become a power hungry device and powering IT equipment is one of the largest operating expenses and challenge for data centre in USA. According to the data published by Electric Power Research Institute (EPRI), USA global data centres cloud power market is expanding at over 10% annually to reach 200 billion kilowatt-hour energy consumption by 2020. Reducing power loss by 1% inside a server power supplies could result in 2 billion kilowatt-hour energy saving. SCALDO is a patented technique developed by the power electronics research group, University of Waikato which improves the efficiency of low drop-out regulators. This technique can be used inside silver box power supplies to enhance the quality of the output power. Practically realising some SCALDO configuration is challenging due to its large switch count. Novel power converter topology presents in this paper helps SCALDO to be used efficiently inside silver box power supplies with electrical isolation and reduced number of switches.
