摘　　要：混合SiC IGBT采用SiC肖特基二极管替换传统IGBT器件中的反并联二极管,可以减少二极管反向恢复损耗和IGBT开通损耗,相对于传统的Si IGBT器件,其性能大幅提升,相比于高压大功率全SiC器件,混合SiC IGBT在成本和技术成熟度方面具有较大优势。文章根据混合SiC IGBT器件特性开发了符合混合SiC IGBT器件应用需求的低换流回路杂散电感的变流器模块,研究了换流回路杂散电感对混合SiCIGBT开关特性的影响。试验结果表明:变流模块杂散电感对混合SiC IGBT开通振荡电压幅值与持续时间具有较大的影响;使用混合SiC IGBT器件比使用Si IGBT器件可以降低约25%的系统损耗。Hybrid SiC IGBT uses SiC Schottky diode to replace the anti-parallel diode in traditional IGBT devices, which can reduce the diode reverse recovery loss and IGBT turn-on loss. Compared with the traditional Si IGBT device, the performance of hybrid SiC IGBT is greatly improved, and compared with high-voltage and high-power all SiC devices, hybrid SiC IGBT has greater advantages in cost and technology maturity. According to the characteristics of hybrid SiC IGBT devices, a converter module with low stray inductance in converter circuit was developed to meet the application requirements of hybrid SiC IGBT devices, and the influence of stray inductance of converter circuit on switching characteristics of hybrid SiC IGBT was studied. The experimental results showed that the stray inductance of converter module had a great influence on the amplitude and duration of switching on oscillation voltage of hybrid SiC IGBT, and the system loss could be reduced by about 25% by using hybrid SiC IGBT devices.
