摘要
IPOSIM是一个功能强大的IGBT仿真工具,能够计算IGBT和续流二极管的开关损耗和导通损耗,仿真其温度分布和结温纹波。本文简单介绍了计算IGBT损耗的基本理论和相关热分析模型以及应用该工具的相关原则。同时,又介绍了一些最新的功能,如能够比较不同IGBT模块在不同开关频率条件下输出电流能力的大小;自定义负荷能够完成在给定的变频器负荷条件下IGBT的仿真分析。最后给出了一些应用该工具的仿真技巧和实例。
IPOSIM is a powerful tool of IGBT simulation. It can calculate switching and conduction losses for IGBT and freewheeling diode, and simulate temperature distribution andjunction temperature ripple. An enhanced function is also the benchmark of current output capability of different IGBT modules at different switching frequency in the latest version. The load cycles function is for inverter simulation at specific application conditions. Some tips and skills are presented in the paper.
