Comparing to the most common reliability tests this work presents a new approach of accelerated testing, by combining temperature, humidity and pressure cycling with voltage stress. A design of experiments methodology has been proposed to test IGBT inverters and understand environmental factors effect. The humidity-pressure combination effect is studied for various IGBT inverter packaging materials.
