摘要
母排的分布电感是影响高压大容量变换器中半导体器件可靠运行的重要因素。以一台基于集成门极换流晶闸管的三电平变换器中的母排为研究对象,采用部分元等效电路法建立母排模型,提出一种低感低影响母排布局和分配的设计方法,并将该方法用于实际系统中。提出一种新的母排结构,其仿真结果与原有结构的实验、仿真结果对比表明,采用本文所提出的母排设计方法,可有效地减小母排的分布电感及其对开关器件电压应力的影响。
Busbars have serious influence on the power converters. The busbars in an IGCT-based high reliability of semiconductor devices in high power three-level converter are studied. The busbaxs＇ model is developed by employing partial element equivalent circuit （PEEC） technique. A low-inductance and low-effect design method of busbar is proposed. Based on the method, a new structure of the busbar is obtained. The simulation and experimental results prove that the busbar design method proposed in this paper can reduce the distributed inductance and the induced voltage peak on the switches effectively.
