Design, simulation and implementation of FOC-SVM DCMLI driven PMSM drive

This paper presents design, simulation and implementation of field oriented control (FOC) space vector modulation (SVM) diode clamped multilevel inverter (DCMLI) driven PMSM drive using AVR microcontroller. For better speed control of PMSM, FOC is widely used. The main drawback of three-phase conventional bridge inverter is lower dv/dt stresses, lower electromagnetic compatibility and smaller rating as compared with multilevel inverters. The PMSM merits are high power-to-weight ratio, high efficiency, and rugged construction; it is also a better candidate in automotive application. In SVM principle, all three drive signals for the inverter will be created simultaneously and implemented for generation of pulses in the inverter. Simulation is done by MATLAB and experimental implementation of DCMLI with resistive load using AVR microcontroller. The comparative torque, current and harmonic analysis of inverter driven PMSM drive with SVM were analysed. The proposed PMSM drive gives better control performance of speed and torque, less distorted output and less harmonic distortion.
