Influence of High-Frequency Operation on the Efficiency of a PMSM Drive

This paper thoroughly examines how high-frequency switching and a high fundamental frequency impact the parameters and efficiency of a high-speed permanent magnet synchronous machine (PMSM). We carefully study how to design and model these motors considering these high-frequency effects. We use theory, computer simulations, and real-world tests to make sure our approach is sound and reliable. By doing this, we aim to better understand how these high-frequency factors influence the performance of the motor.
