Thermal considerations on highly integrated module for small power drives

High integration of power electronic systems require optimised packages. This paper presents an innovative, fully-molded intelligent power module for small power three phase drives in a dual-in-line package. The package itself offers the possibility of integrating additionally the input bridge rectifier. The paper discusses the thermal performance of the module concept by working out the impact of the rectifier loses in respect of case temperatures. The overall losses balance is calculated and the result is compared with measurements while operating the module with and without input rectifier.
