Direct Torque Control for Matrix Converter Driven PMSM
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2014, Vol 2, Issue 10
Abstract
This paper carries work on application of direct torque control for Five-Phase permanent magnet synchronous motor drives. In recent years, only voltage source inverters (VSIs) have been used to supply five-phase drives, but Matrix converters (MCs) pose many advantages over conventional VSIs, such as lack of dc bulk capacitors, high quality power output waveform and higher number of output voltages. Due to some special applications of multiphase machines such as ship propulsion and aerospace, the volume of these drives is an important challenging problem. In this paper, direct torque control (DTC) algorithm using a three-to-five phase Matrix Converter is proposed for five-phase permanent magnet synchronous motors (PMSMs). Because of higher number of output voltages in MCs, there is a greater degree of freedom to control the torque and flux. In other words, this proposed method use the advantages of both DTC method and MCs. Simulation results show the effectiveness of presented method.
