摘　　要：随着IGCT器件技术发展,IGCT器件关断电流逐步增大,使得IGCT器件应用至柔性直流输电成为可能,与IGBT器件相比,IGCT具有电压等级更高、损耗更低、价格便宜等优势。在此介绍了IGCT-MMC子模块拓扑结构,研究了IGCT-MMC子模块开通关断电气特性,并对子模块吸收回路参数进行了设计,基于6 500 V/3 800 A IGCT器件子模块样机,完成了相关试验验证,试验结果表明了IGCT-MMC方案的可行性。With the development of IGCT device technology,the turning-off current of IGCT devices is gradually increasing,which makes it possible to apply IGCT devices to flexible direct current transmission,compared with IGBT devices,IGCT devices have advantages such as higher voltage levels,lower losses,and lower prices.The topology structure of the IGCT-modular multilevel converter(MMC)submodule is introduced,the electrical characteristics of the ICCT-MMC submodule on/off are studied,and the absorption circuit parameters of the submodule are designed.A submodule prototype based on 6500 V/3800 A IGCT devices is developed,and relevant test verification is completed,the test results show the feasibility of the IGCT-MMC scheme.
