摘要：In this paper, a new direct torque control strategy for induction machine based on indirect matrix converter is introduced and investigated. In the inverter stage, the classical direct torque control method is employed. In the rectifier stage, the outputs of flux and torque hysteresis comparators, generated based on the request signals for flux and torque, are used to produce the switching signals for the switches directly and without any need for an additional control unit. In this method, the input current is nearly sinusoidal and the input displacement angle is adjustable. Moreover, zero current switching can be implemented in the rectifier stage through inserting short periods of zero voltage vector in the inverter stage. Using this control strategy, the advantages of indirect matrix converter and direct torque control method are combined. Steady-state and transient behaviors of the system are simulated using PSIM simulation package and simulation results are used to verify the effectiveness of the proposed strategy and support the analytical results.
