摘要
设计了一款高密度、高可靠性的三联对称式三电平IGCT相模块,其电气、压装、冷却被一体化高度集成,解决了多重平板型半导体器件压装、高压低电感柔性母排连接、高效冷却管网布局等技术难题;其换流路径对称,杂散电感可控制在120nH以内。试验结果表明,该相模块的输出达2000A(rms)/4840V(DC),可将单传动变流器容量提升至11MVA。
It designed a tri-linked structural symmetry IGCT phase module based on NPC three-level circuit with high density and high reliability. Its electrical design, press mounting design and water-cooling design are highly integrated within one unit. Variety of technical problems were overcome, such as multi-press mounting of plate semiconductor, high-voltage-low-inductance flexible busbar connection, high efficiency cooling pipe net distribution, etc. Commutation path of the module is symmetric and its stray inductance can be controlled within 120 n H. Experimental results show that output current of the phase module can be up to 2000A(rms) at DC 4 840 V and the capacity of single driving converter can be promoted to 11 MVA.
