Abstract

The efficiency of the system decreases with increasing switching frequency in high-power density industrial driving applications. In order to increase the system efficiency, reliability, and power quality in a high-power drive system, power losses are becoming more crucial to calculate precisely in the industrial drive. In this study, the switching and conduction losses in a 370 kW industrial motor driver with 1000V DC bus voltage are calculated with the information obtained from the datasheets and modeled in detail for three different insulated-gate bipolar transistor (IGBT)/diode modules on the MATLAB/Simulink environment. Thanks to the obtained model, the losses can be optimized for different switching frequencies, and the performance of the system in terms of losses and efficiency can be examined in the case of using different IGBT/diode modules.
