۲۴-Sector Direct Torque Control for Multilevel Drives

This paper gives a detailed analysis of direct torque control (DTC) strategy in a five-level drive and proposes a ۲۴-sector switching table. The overvoltage problem due to high dv/dt is reduced compared to the ۱۲-sector DTC. Using all vectors leads to better flexibility and reduces speed oscillations. Simulation and experimental results for a ۳kVA prototype confirm the proposed solutions. A TMS۳۲۰F۲۸۱۲ is used to implement the above strategy.
