Dynamic electro-thermal modeling in Power Electronics Building Block (PEBB) applications

Abstract

This paper proposes a dynamic electro-thermal methodology via a reasonable iterative algorithm for Power Electronics Building Block (PEBB) application. The modeling includes an improved power loss distribution model which has temperature dependent self-improvement ability and an effective thermal model providing a fast temperature calculation, which can be integrated with electrical model directly. Simulation results are eventually presented to verify the effectiveness of the proposed modeling method in an PEBB application. The proposed dynamic electro-thermal model is proved that it can provide fast and accurate information for shifting PEBBs in their parallel operation and thus improve the PEBB's efficiency and semiconductor's life time. © 2010 IEEE.
