Field Oriented Control of Space Vector Modulated Multilevel Inverter fed PMSM Drive

Abstract

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.
