SiC JFET SJEP120R063特性分析及其在逆变器中的应用

摘要

介绍了SiC NET SJEP120R063的工作特性,由于该器件正向损耗低,可有助于提高大功率逆变电路的开关频率和工作效率.设计了采用SJEP12OR063实现的三相逆变器,并进行了实验研究,结果表明用具有较小的导通电阻和正向损耗的SJEP120R063,逆变器的工作效率可以提高到98%.%The paper introduced the characteristics of SiC JFET SJEP120R063,it can improve high power inverter's switching frequency an d work efficiency owed to its lower switching loss, designed three phase inverter based on SJEP120R063,the component has lower drain-source on-resistance and forward loss. Experimental results indicate that the efficiency of SJEP120R063 inverter can be improved to 98％.
