Direct Torque Control of Induction Motor Drives Using High Frequency Pulse Density Modulation for Reduced Torque Ripples and Switching Losses

摘要

A direct torque control (DTC) based on a high frequency AC (HFAC) power converter is proposed. The scheme exploits the recent advances in soft switching and pulse density modulation (PDM). The proposed HFAC-DTC scheme demonstrates the potentials of superi
