摘要
绝缘栅极晶体管(IGBT)作为功率半导体器件有着重要地位,并被广泛使用。针对中低速磁浮列车悬浮控制系统中悬浮斩波器核心功率器件IGBT进行近似电路仿真分析,研究IGBT快速开关过程中产生的巨大瞬时功率问题。为节约研发周期,降低设计成本,利用电子仿真软件PSpice建立IGBT的计算机仿真模型,对指定型号的IGBT进行静态特性、动态特性以及工作状态仿真,并通过仿真结果计算开关损耗,为以后IGBT模块在高功率设备中的开发使用打下基础。
As a power semiconductor device,insulated gate bi-polar transistor(IGBT)plays an important role and is widely used.This paper analyzes the approximate circuit simulation of IGBT,the core power device of suspension chopper in the suspension control system of maglev train with medium and low speed,and studies the huge instantaneous power problem in the fast switching process of IGBT.In order to save the research and development cycle&reduce the design cost,this paper uses electronic simulation software PSpice to establish the simulation model of IGBT,and simulates the static state,dynamic state and working state of IGBT for the specified model.The switch loss is calculated by the simulation results,which lays a foundation for the development and use of IGBT module in high power equipment.
