New Sensorless Permanent Magnet Synchronous Motor Drive
… operations. Among these techniques, pulsating high-frequency signal injection (PHFSI) stands out as a commonly used technique in various industrial applications. However, a significant limitation arises when applying the PHFSI technique in surface PMSMs (SPMSMs) due to the absence of magnetic …

Direct Torque Control for Silicon Carbide Motor Drives
… uncertainties, and external disturbances. Using higher switching frequency is generally required by DTC to reduce the torque ripples and decrease stator current total harmonic distortion (THD), which however can lower the drive efficiency. Through the use of the emerging silicon carbide (SiC) …
