摘 要: | 绝缘栅双极型晶体管(insulated gate bipolar transistor,IGBT)是换流阀子模块的核心器件,研究其抗短路能力对于提高换流阀可靠性具有重要意义。根据模块化多电平换流阀的运行机理,设计了一种换流阀子模块IGBT短路试验回路与系统,进行了换流阀在稳态运行下IGBT短路故障试验,从而实现对IGBT的稳态应力和短路故障下的暂态应力综合考核。最后通过试验平台进行验证,结果表明所提试验回路和系统的正确性。

Abstract: | As the key device of sub module of converter valve,IGBT is of great practical significance to improve the reliability of the converter valve by studding the anti-short circuit ability of IGBT.Based on the operating mechanism of modular multilevel converter valve,this paper proposes an IGBT short circuit test circuit and system of sub module of converter valve.A comprehensive assessment of the transient stress by short fault and the steady stress of the converter valve is achieved.The validity of test circuit and system is verified by proposing a test platform. |
