Abstract :
A calorimetry-based apparatus for accurate loss measurement of integrated power electronics modules (IPEMs) is presented. The IPEM is placed in a closed chamber, and a heat flux sensor is implemented to measure the total heat generated in the IPEM. Thermoelectric modules are introduced to cool the IPEM and control the operating temperature of the IPEM. The temperature difference between two polished covers in the apparatus is controlled in order to reduce the measurement error caused by convection and radiation. The design and analysis of the proposed apparatus, which can measure losses up to 50 W is described below.
