摘要
介绍了非对称型门极换流晶闸管的P基区结构.在建立门极换流晶闸管器件模型基础上,利用MEDICI软件分析了P基区结构对门极换流晶闸管通态特性的影响.模拟结果表明,P基区的掺杂浓度和宽度对门极换流晶闸管通态压降有着重要的影响.通过调节P基区的浓度和宽度,可以有效地改善门极换流晶闸管的通态特性.
In this paper, the structure and mechanism of P base region of asymmetry Gate Controlled Thyristor are briefly introduced. On the basis of Gate Controlled Thyristor model, the influence of the structure of P base region on on - state characteristic is analyzed using MEDICI simulator. Simulation results show that the doping profile and width of P base region are important to the on - state voltage drop of Gate Controlled Thyristor. On - state characteristic of Gate Controlled Thyristor can be improved effectively by adjusting the concentration and width of P base region.
