Abstract

Matrix converter rather than voltage source inverter can be used as high-performance technique supplying electric motor in direct torque control (DTC). DTC's most significant deficiency in induction motor, magnetic torque ripple, can be markedly reduced by appropriate space voltage-vectors whose influence on stator flux and electromagnetic torque in DTC of induction machine that uses "matrix converter" the subject of this work. DTC degrees of freedom were shown seriously limited by 60° flux sectors, thus division to twelve 30° sectors of flux-space vector hexagon is proposed. The increased "matrix converter" degrees of freedom were then extracted for DTC implementation.
