Thermal Characterization and Comparison of Intelligent Power Modules for Permanent-Magnet Synchronous-Motor Drives

In this thesis Intelligent Power Modules to drive PMSM drives are discussed. Regulations and a more conscientious way to look at how we use electrical energy to supply products are leading towards the use of more efficient technologies in any sector of the Electrical engineering. IPMs, as a way to supply electrical motors, push in this direction as well. This work shows how to best take advantage of them describing their characteristics and advantages, the design of IPM-based systems, and address the main challenge they pose: thermal issues and heat dissipation

5 PREFACE The aim of this master’s degree thesis, developed in collaboration with STMicroelectronics in Catania, has been the investigation of the thermal properties of the newest device of the family of IGBT Intelligent Power Modules (IPMs) manufactured by the company. As is known, international treatises between countries like the most-cited “Kyoto protocol” established the commitment by the countries signers of the agreement in reducing the emission of several greenhouse-gases (GHG) like carbon dioxide, methane, nitrous oxide, sulphur hexafluoride. A key role in the reduction of the emission of carbon dioxide is covered by electric motors. In fact they are responsible of the largest consumption of electric energy and, because most of electric energy produced in the world is derived by coal, gas and other non-renewable sources, they take charge of the greatest “carbon footprint”. For this reason, even small improvements in the field of electric motors would greatly benefit the environment and lead to more self- sustainable energy supply for the countries. An indirect but strategic role is instead played by power electronics. The conversion and control of the power electrical/electronic systems cover a fundamental role for the efficient operation of whatever larger system: electrical, electromechanical, electronic and so on. Improvements in the field of power electronics can regard several parts of it, like circuit topologies, control techniques, power devices, CAD software and so on. As mentioned in the beginning, this thesis has regarded the analysis of the thermal properties of a particular power electronic device belonging to the great family of Intelligent Power Modules, of which the ultimate goal is a more efficient conversion of the
