Validation of Infrared Camera Thermal Measurements on High-Voltage Power Electronic Components

Thermal performance of power electronic components Is a limiting factor on the power density and design of high-voltage, high-power systems. Therefore, accurate assessment and characterization of the thermal capabilities of these components is critical for the development and design of high-density power applications. This paper demonstrates the efficacy of using an infrared camera system to characterize high-voltage power electronic components. A comparison is given for the use of two different spray coatings to create a uniform surface emissivity within a variety of experimental situations.
