The developed models is utilized in this chapter for investigating thermal characteristics of DC–AC inverters. The physical properties and performance of a commercially adopted inverter chip was studied and realistic model was derived to understand its behavior. Subsequently, model’s outcomes and performance was experimentally evaluated using purposely constructed test rig. The experimental validation of thermomechanical finite element model and the proposed switching control method with variable DC link operation were achieved via dSPACE RTI by using a three-phase inverter module; namely the FS10R12VT3 by Infineon Technologies. This device is a scaled-down module of the FF1000R17IE4 which is constructed with six pairs of IGBT/diode chips. It is more suitable to be tested under laboratory condition due to its low-power capacity.
