摘要

本文介绍了一种具有水冷热管冷却系统的绝缘栅双极晶体管（IGBT）的电热模型的开发。首先，建立了热管冷却系统的热模型。然后，建立了IGBT的电热模型来预测瞬态操作中的结温变化。在电容集总法的基础上确定了IGBT的热模型。通过考虑结温对IGBT静态电学参数的影响，建立了IGBT的电学模型。最后，在升压转换器的应用中考虑了电热模型。模型预测显示了热管冷却系统在不同换相频率下的有效性。事实证明，热管冷却系统可以将IGBT的结温保持在允许安全运行的值。

Electro-Thermal Modeling of Power IGBT Module Cooled by A Heat Pipe Cooling System

This paper deals with the development of an electro-thermal model of an Insulated Gate Bipolar Transistor (IGBT) with a water-cooled heat pipe cooling system. Firstly, a thermal model of the heat pipe cooling system is proposed. Then, an electro-thermal model of the IGBT is developed to predict the junction temperature variations in transient operation. The thermal model of the IGBT is determined on the base of the thermal-capacitance lumped method. The electrical model of the IGBT is developed by considering the effect of the junction temperature on its static electrical parameters. Finally, the electro-thermal model is considered in a boost converter application. The model predictions show the effectiveness of the heat pipe cooling system for different commutation frequencies. It is proved that the heat pipe cooling system can keep the junction temperature of the IGBT at values allowing safe operation.
