Abstract

This paper explores the application of a Peltier thermoelectric module in selectively correcting unbalanced temperatures of multiple power dies in SiC power modules. This supportive cooling can address thermoelectric effects’ advantages without demanding substantial powers needed to create a meaningful temperature gradient. Our concept is validated by two-step multiphysics finite element (FE) simulations. For conservativeness, the first simulation models a commercial Peltier module, instead of state-of-art materials, and confirms similar thermal characteristics with its datasheet. In the second simulation, the developed Peltier model is now integrated with an example SiC power module having a not-optimized liquid cooler. Simulation results exhibit better balanced die temperatures in this simulation condition.
