This paper gives a detailed analysis of direct torque control (DTC) strategy in a five-level drive and proposes a 24-sector switching table. The overvoltage problem due to high dv/dt is reduced compared to the 12-sector DTC. Using all vectors leads to better flexibility and reduces speed oscillations. Simulation and experimental results for a 3kVA prototype confirm the proposed solutions. A TMS320F2812 is used to implement the above strategy.
