Design and Implementation of 50V/400A Single-Stage Full-Bridge Synchronous Rectifier for Data Center Application

Synchronous rectification (SR) is widely adopted for low-voltage high-current applications to improve efficiency. However, most SR researches focus on low power levels at hundreds or several kilowatts, and there is yet any attempt to extend SR to tens of kilowatts. This paper presents the design and experimental results of a full-bridge SR using ON-Semi NCP4305 SR IC at 20kW for 48V data center application.
