Research on power electronic integrated module for SMPS

A novel module structure of power module for switching power supplies is presented in this paper. The power module employs the three-dimension terrace structure to produce less parasitic parameter and higher power density. Based on this structure, the performance of the power module, such as parasitical parameters and thermal management performance, is evaluated through simulation analysis and experimental research. The results with measurement on a 1kW prototype demonstrate that the power module based on the Aluminum substrate has high power density, less volume and better thermal performance, compared with conventional structure equipment
