【Abstract】 Thermal measurement and analysis of three typical power devices in the application of aviation are developed. The thermal measurement is carried out using an infrared thermo-video system. The results play an important role in the reliability analysis for the power devices. Numerical simulation, which qualitatively provides results to improve the thermal analysis of the devices, is also presented.更多还原
