| 摘 要： | 模块化多电平整流器(modular multilevel converter,MMC)子模块具有承受高电压、大电流等特点,绝缘栅双极型晶体管(insulated gate bipolar transistor,IGBT)又是子模块的关键器件,而IGBT的损耗和结温计算方法决定IGBT的热设计和选型,是影响其在MMC工程应用的关键因素。文中首先对MMC稳态运行时子模块承受的应力进行了分析,其次,结合通态电流、子模块的投切和结温估算模型,设计了一种IGBT损耗和结温的计算方法,最后在搭建的试验系统中进行验证,结果证明了所给出的计算方法有效可行。

| Abstract: | The electrical stress of high voltage and high current is the characteristics of the sub module base on MMC.And IGBT is the key component of MMC module.A calculating method for loss and junction temperature of IGBT base on MMC is very important to the heat design and type selection of IGBT in MMC engineering application.Firstly,the stress of the module under steady state operation of MMC is analyzed.Secondly,a method for calculating the IGBT loss and junction temperature of MMC module is given with current and sub module switching and junction temperature estimation model.Finally,the calculation method is verified in the back to back test system.The proposed method is proved to be effective and feasible. |
