基于氮化镓的反激同步整流DC/DC变换器设计
Design of Synchronous Rectifier Flyback DC/DC Converter Based on GaN
摘要
Abstract
A design method for small-and medium-power DC/DC converters suitable for low-orbit commercial aerospace is given in this paper.A synchronous rectifier flyback topology and surface mounted devices are adopted,which can meet the demands for common single-and multi-output DC/DC converters applied in aerospace,with advan-tages of low cost,high performance,high reliability,and mass production.To further improve the conversion efficiency and power density,gallium nitride(GaN)FETs are also used.In addition,the losses of main power devices in the topol-ogy under different operating conditions are calculated and compared.Finally,a DC/DC converter with a wide range of input voltage(23-47 V)and output of 5 V and 30 W was built for verification.关键词
