摘要：

This paper gives a detailed analysis of direct torque control (DTC) strategy in a five-level drive and proposes a 24-sector switching table. Also, flux estimation has been improved by a discrete-time low-pass filter (LPF) with variable cut-off frequency. Algorithm to compensate the amplitude and phase errors is introduced and algorithm to determine digital filter coefficients at different speeds is presented. Simulation and practical results on a prototype using an induction motor 400V, 3kVA are given. To implement the DTC strategy, processor TMS320F2812 is used.
