电机控制器IGBT模块是实现电能转换和电机控制的重要组件之一，通常在复杂工况下工作，其可靠性对整个电驱动系统的稳定至关重要。一般情况下，IGBT的损耗分析采用手册公式法直接求取，忽略了温升对IGBT模块的影响。针对此问题，提出1种热耦合分析的方法，首先建立IGBT模块的损耗计算模型，在此基础上构建热网络模型进行结温估算，再用温升估算结果修正损耗计算模型；搭建了电机控制器仿真模型，对IGBT结温和损耗进行仿真，并通过电机温升实验，验证了该热耦合分析方法的有效性。

The IGBT module of a motor controller is one of the important components for realizing electric energy conversion and motor control. This module usually works under complex conditions, and its reliability is crucial for the stability of the whole electric drive system. In general, the IGBT loss is directly calculated using the method of manual formulas, which ignores the influence of temperature rise on the IGBT module. Aimed at this problem, a method of thermal coupling analysis is proposed. First, a loss calculation model of IGBT module is established. On the basis, a thermal network model is built for the estimation of junction temperature, and the temperature rise estimation result is further used to correct the loss calculation model. A simulation model of the motor controller is constructed, and the junction temperature and loss of IGBT are simulated. In addition, the effectiveness of the proposed thermal coupling analysis method was verified by the results of a temperature rise experiment conducted on the motor controller.
