Abstract
In the current industrial scenario, power modules are the most crucial electrical component used by any motor drive. Power modules are exposed to harsh environmental conditions. So, in order to design a reliable and high-quality product, lifetime estimation becomes a necessary task. In this paper, a simplified version of Coffin–Manson law along with rainflow algorithm has been used to develop analytical lifetime estimation method of IGBT modules. Load profile for an application of washing machine is taken into consideration. Direct torque control method of speed control has been used. Practical IGBT module has been electro-thermally modeled using PLECS toolbox. Finally, Palmgren-Miner law is used to sum up all the damages of fatigue cycles, and lifetime of the IGBT module FS150R12KT4 has been predicted. © 2021, Springer Nature Singapore Pte Ltd.
