DTFC-SVM based Five-level cascaded Inverter with reduced switches fed Interior Type Permanent Magnet Synchronous Motor Drive

Impact Evaluation of Innovative Selective Harmonic Mitigation Algorithm for Cascaded H-Bridge Inverter on IPMSM Drive Application

“…In this field, the permanent magnet synchronous machine (PMSM) is the most employed due to it is peculiar features such as high efficiency, high torque density, and wide operating speed range [12]- [14]. In literature, there are a huge amount of studies concerning the benefits deriving by the use of multilevel inverters on PMSM electrical drives [15]- [19]. In detail, many control techniques have been proposed.…”

“…The main control techniques discussed are direct torque control (DTC), model predictive control (MPC), and field-oriented control (FOC). The DTC presents the advantages of simplicity and robustness but presents the drawback of variable switching frequency and high torque ripple [15]- [16]. The MPC allows to obtain a very high dynamic performance but the implementation is complex and requires a large amount of calculation [17]- [18].…”

“…However, the scientific literature includes very few studies on the performance of PMSM electric drives fed by CHBMI with SHM modulation algorithms. Most of the studies focus the attention on PMSM electric drive performance by the use of Space Vector Pulse Width Modulation (SVPWM) both with traditional two-level inverters and with multilevel inverters [6], [15]- [16], [19], [32], [37]- [40]. For this reason, the main purpose of this work is to investigate the performance of IPMSM electric drives fed by five-level CHBMI with the SHM algorithm.…”
