Analysis of SiC based power electronic inverters for high speed machines

Abstract

Silicon carbide (SiC) based power switching devices have been extensively studied by researchers and engineers in recent years because of their superior physical properties compared to silicon. However, the benefits of using SiC devices have yet to be fully explored, especially for high-speed or high-fundamental frequency motor drive applications. Hence, this paper contributes to the understanding of the benefits of SiC inverters as applied to high-speed or high-fundamental frequency drives. This research investigates the high switching frequency capabilities of SiC inverter to improve the performance of high-speed machines or high fundamental frequency operation and achieve lower weight and volume of the both motor and inverter.
