Comparison of modeling switching losses of an IGBT based on the datasheet and an experimentation

Résumé

This paper focuses on the prediction and the study of the veracity of a losses model (both conduction and switching losses) in IGBT power modules used for electric vehicle applications. This article shows a test case based on an experimental estimation of losses with a double pulse test circuit and a circuit model based on the use of ANSYS solver Circuit - Simplorer©. This modeling is only linked to the knowledge of the IGBT characteristics obtained from datasheets. Then, it is compared with experimental measurements. The veracity of these models is evaluated, the errors are quantified and if necessary, additional characterizations that will be performed to complete the data from datasheets will be identified. An estimation of the losses with sufficient accuracy will be obtained for different switching conditions (voltage, current, temperature, gate resistance).
