压接式IGBT模块的动态特性测试平台设计及杂散参数提取
Dynamic Switching Characteristics Test Platform Design and Parasitic Parameter Extraction of Press-Pack IGBT Modules
摘要
Abstract
Press-pack IGBT modules have great potential applications in the field of large capacity power electronic conversion systems such as voltage-source-converter-based high-voltage-direct-current (VSC-HVDC), due to their excellent characteristics of good heat dissipation, low stray inductance, short circuit failure mode and so on. However, their dynamic switching characteristics have been not clearly illustrated, which has deeply restricted their industrial application. In this paper, a dynamic switching characteristics test platform for press-pack IGBT modules was designed and implemented, where the principle of double pulse test was employed. Then through Ansoft Q3D, the extraction method, distributions and impacts of the parasitic parameters were explored. Moreover, the extracted parasitic parameters were validated by experimental results. It is shown that the laminated busbar technology and the snubber capacitors can effectively reduce the device turn-off voltage overshoot and provide the reasonability of the test platform design.关键词
