摘要
介绍了基于数学模拟方法的IGBT损耗计算模型以及计算IGBT结温所采用的等效热路模型,在此基础上提出了一种连续工作损耗和瞬时结温计算方法,并针对器件生产厂家提供的计算软件存在的限制和不足问题,开发了一款新的损耗和结温计算软件。仿真及样机实测数据证实了所述损耗和结温计算方法及计算软件的有效性。
It introduced a calculation model of IGBT loss based on mathematical simulation method and an equivalent thermal circuit model for IGBT junction temperature calculation,and then put forward a calculation method of continuous loss and instantaneous junction temperature. Considering the limit and deficiency of the calculation software provided by the device manufacturer, it developed a new calculation software. Simulation and actual prototype test data confirmed the effectiveness of the calculation method and calculation software for loss and junction temperature.
