摘要

对功率模块中IGBT和二极管的瞬态芯片温度进行了研究。芯片温度和功耗的在线计算是在单片机中完成的。在不同负载周期和输出频率下，在相同的平均负载电流下，用降压变换器取得了先进的实用效果。文中还对结果和误差进行了分析。

Real time calculation of the chip temperature of power modules in PWM inverters using a 16 bit microcontroller

Investigations of the transient chip temperature of IGBT and diode in power modules are presented in this paper. The calculation of chip temperature and power losses occurs on-line in a microcontroller. Advanced practical results achieved in a step down converter are shown at different load cycles and output frequencies with the same average load current. An analysis of results and errors is also shown.
