Abstract

This paper presents the field-oriented control (FOC) of a five-phase induction motor (FPIM) fed from a three-to-five phase direct matrix converter (DMC). The article focuses on the modulation and control of the three-to-five phase DMC, which discusses minimizing the problems associated with switching vector selection, sector identification, switching sequence selection, and dwell-time calculations. The DMC is controlled from the space vector pulse width modulation (SVPWM) technique, eliminating the x-y components of space vectors. Moreover, the matrix converter can perform unity power factor control at the input side. The FPIM is sourced from a DMC, and the FOC technique is applied to control the drive. The dynamic characteristics of the drive are succeeded for different loading conditions. The proposed work is simulated in Simulink/Matlab environment and further verified through practical experimentation. The control signals of the IGBTs are generated through FPGA embedded in dSPACE 1006. The experimental and the simulation results prove the practicability of the FOC to FPIM fed from a DMC.

Summary

INTRODUCTION

Simple construction, cost-effectiveness, and ruggedness a re the ma in rea sons for the preference for threephase drive systems. The virtual vectors control concept has been utilized to perform the model predictive direct torque control for a five-phase induction motor fed from a direct matrix converter [25]. This research work proposes SVPWM based FOC method to eliminate this xy component by using the volt-sec balance technique to modulate active voltage vectors in a switching cycle [29]-[30]. For this implementation, the paper presents a precise modulation of three-to-five phase DMC, which can solve the problems related to switching states, sector identifica tion, switching sequence selection, a nd dwell-time calculations. The proposed method in an electric drive has been verified experimenta lly in the la b with a five-pha se induction motor
