摘要
工业应用中需要根据工况选用合适的IGBT模块,不能直接参考模块数据手册上的数据来应用模块。本文针对特定的应用工况搭建硬件和软件电路,进行全面自动化双脉冲测试,分析了各工况条件对开关特性的影响,为IGBT模块的实际工况运行优化设计以及功率能力评估提供参考。同时,还提出了一种驱动电阻的优化切换方法和一种最佳驱动电路和驱动参数的选择方法。
In industrial applications,it is necessary to select an appropriate IGBT module according to the actual operating conditions.As a result,the module cannot be applied by directly referring to the data specified in a power module datasheet.In this paper,hardware and software circuits for specific application conditions were built to conduct a fully automated double-pulse test and analyze the impact of each operating condition on the switching characteristics,providing reference for the optimal design of the actual operating conditions of the IGBT module as well as its power capability assessment.Finally,an optimized switching method for the driving resistor and a selection method for the optimal driving circuit and driving parameters were proposed.
