In this article, field orient control (FOC) of a space vector modulated asymmetrical Multilevel inverter (MLI) fed Permanent Magnet Synchronous Motor (PMSM) is presented. The MLI considered is a reduced switch inverter which produces seven level output with six power switches and two input sources. A general low computational space vector algorithm is used to modulate the MLI. The PMSM is controlled by Field oriented control with speed regulated PI. The implementation of the FOC applied to a PMSM and validated with simulation results. Simulation of the whole system is carried out in MATLAB/simulink tool. © 2017 The Authors.

Energy Procedia

Multilevel inverters (MLI) are employed mainly to enhance the performance of the drive scheme which generally demands a quality power source. The modulation technique involved plays a vital role in its improvement. The conventional sine pulse width modulation (SPWM) scheme employed in this regard though suffers from various limitations resulting in drives with lesser efficiency. Hence Space Vector Pulse Width Modulation (SVPWM) techniques are becoming popular in inverter systems due to its advantages in better utilization of input voltage, lesser harmonic content and better output voltage profile, especially from the drive system point of view. The disadvantage being the complex computations involved. This paper envisages to identify the optimal SVPWM technique for diode clamped MLI. The conventional SVPWM and the proposed SVPWM techniques are applied to the diode clamped MLI fed induction motor drive. The performance of both the drive schemes are analyzed and compared, to show the effectiveness of the proposed method. The added advantage of the proposed technique is that it involves lesser computations and has generalization capability. © 2015 IEEE.
