HI,IPOSIM计算结温背后的引擎是PLECS,那如果我用PLECS搭建一个电路并且对IGBT进行热路仿真,然后将PLECS中搭建的电路的工况提取填入IPOSIM中进行"Load cycle simulation",冷却条件的填入有什么注意事项?能和PLECS搭建的散热器模型条件保持一致吗?如果可以与PLECS的散热条件一致,其他参数也能一致,那用IPOSIM计算结温和功耗的结果会和PLECS计算得到的曲线一样吗?

 您好,

1, 关于冷却条件的注意事项请参考help of defining heatsinks. 如下图所示:

对于2.3问题,只要建模与IPOSIM中的参数一致,在PLECS中也可以得到和IPOSIM同样的结果。

Best regards,

Rachel

谢谢您的回答,我还想请问这三个散热条件填入有什么区别?

Dear  

您好,三个不同的散热器模型对应右边不同的散热器参数。您可以根据设计需要进行选择。
