Thermal Design and Optimization Methodology for Integrated Power Electronics Modules

摘要

A methodology was developed and implemented to optimize the design layout for integrated power electronics modules (IPEMs) by considering both the electrical and thermal performances. This paper is primarily focused on the thermal aspects, which were analyzed using three-dimensional (3D) computational software tools. Implementation of the design methodology resulted in a 70 percent reduction in the common mode current, a 4 percent reduction in the size of the geometric footprint, and a 7℃ reduction in the maximum temperature rise for the case studied, thus, providing an increase in the IPEM's overall performance.
