Abstract
A power supply system for data center racks comprises a main power circuit including a power factor correction (PFC) module and a bypass power circuit in parallel to the main power circuit. During normal operation, the main power circuit provides power output because the output voltage of the PFC module in the main power circuit under normal conditions is higher than the output voltage of the bypass power circuit. When the PFC module in the main power circuit fails, the bypass power circuit provides power output in bypass operation. The bypass power circuit provides power by rectifying a three-phase AC current to produce an output suitable for equipment that uses DC power.
