JEE_V7_N2_RP3 B. Arundhati K. Alicemary Suryakalavathi K. Shankar Journal on Electrical Engineering 2230 – 7176 7 2 19 25 Voltage Source Inverter, SVPWM Technique, PMLSM, DSPACE ds1104 Controller Board This paper proposes speed control of permanent magnet linear synchronous motor using Space Vector Pulse Width Modulation (SVPWM). Among the various modulation strategies Space Vector Modulation Technique is the efficient one because of its better spectral performance, better dc bus utilization and easier digital realization. With SVPWM the performance of PMLSM is improved because it eliminates all the lower order harmonics in the output voltage of the inverter when compared to the conventional SPWM technique. The open loop & closed loop simulation model for SVPWM with PMLSM is constructed using MATLAB/SIMULINK. Hardware is implemented and validated Using dSPACE ds1104 controller board.
