Most commonly the necessary heat is generated by conduction losses in the die. As this does not reflect the loss generation in the application, this paper presents a new approach. The heat is generated by a combination of switching and conduction losses exactly as in the application. The inputs and outputs of two three-phase inverters are coupled in order to achieve circular energy flow and therefore high efficiency of the power cycling test. Furthermore, a novel 3D-printed aluminum module heat sink is designed and utilized to achieve the highest possible temperature dynamic.
