Modeling of Power Losses in High-Power Motor Drives
Electrica, 2023 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
