This paper illustrated a modified strategy of direct torque control for single-phase induction motors. The proposed strategy was based on classical six-sector hysteresis-type direct torque control scheme developed by using stator reference frame. The modification made in this paper led to two control strategies called modified six and twelve sectors, respectively. A switching table was derived based on the voltage vectors generated by the three-leg two-phase inverter topology. Simulations were carried out and performance analysis was presented.
