Three-phase high performance rectifier for 380V DC distribution system in data center application

This paper compares the performances of Voltage Oriented Control (VOC) and Direct Power Control (DPC) with hysteresis loop in three-phase voltage source rectifier (VSR), which can be applied to the front-end rectifier in state of art 380V DC distribution system for green data center. Both systems achieve high power factor, low input current distortion and high efficiency. And the simulation results show higher reliability with VOC strategy while lower distortion and higher power factor in DPC realization.
