资料介绍

IGBT(Insulated Gate Bipolar Transistor)阀是柔性直流换流系统的核心,建立实用准确的IGBT模型,对于模拟电磁骚扰源具有非常重要的意义。在IGBT等效电路基础上,采用复合模型法构造IGBT宽频等效电路模型,利用PSPICE软件的模型参数提取程序Parts分别提取功率MOSFET和BJT的模型参数。在此基础上,从IGBT的导电机理出发,用二极管的势垒电容表征其内部的压控寄生电容,建立其等效电路模型,并利用IGBT数据手册和计算相结合的方式提取寄生参数,仿真其稳态、动态特性。仿真结果和厂家给出的实测结果的对比,验证了该模型的正确性。

Insulated Gate Bipolar Transistor(IGBT) valve was the core of flexible DC converter system. The establish of practical and accurate IGBT model was very important significance Forgetting ready for simulating electromagnetic disturbance source. In order to construct IGBT wide-band equivalent circuit, compound model method was used. Parts program was used to extract the parameters of MOSFET and BJT respectively. On this basis, starting from the conductive mechanism of IGBT, the equivalent circuit model was built by using the internal voltage-controlled parasitic capacitance of potential barrier capacitance diode device, and the parasitic parameters were exact...
