Mathematical Modeling and Numerical Analysis of SPIM Drive Using Modified SVPWM Technique

Abstract

This paper presents a modified space-vector pulse width modulation (SVPWM) technique for a five-level inverter that provides complete control over the multiple space-vector voltages of a six-phase inverter. This technique involves splitting six phases into two three-phase five-level inverters connected in parallel. A six-phase induction motor (SPIM) drive with a distributed neutral is considered as the load. This paper also presents a comparative analysis between the proposed and conventional SVPWM inverter-fed SPIM drives. To investigate the analytical developments and voltage limits, MATLAB/Simulink environment was used in this study. A prototype was developed in the laboratory for analyzing the harmonic components of the phase voltages and currents. The efficacy of the proposed technique was validated by means of comprehensive experiments, and the results discussed herein.

Efficiency analysis of six‐phase induction motor drive using an optimized SVM technique for medium/high power applications

“…In the proposed system 5-level six-phase inverter is controlled using an optimized dual three-phase SVM technique. Usually, a six-phase five-level inverter has 5 6 space-vectors, but when these six-phase space-vectors are divided into two three-phase, then the total number of space-vectors is reduced to 5 3 for each three-phase SVM for controlling the MLI, which consequently reduces the time required for the execution of control algorithm and complexity of the system. 26 The 5-level output voltages of the inverter range from −2V (L 2 ), −V (L 1 ), 0, +V (H 1 ), +2V (H 2 ).…”

“…Therefore, multiphase induction motor drives have become a viable solution to overcome such problems for industrial applications. 2,3 The applications include an electric vehicle onboard charging system, 4 electric traction systems, 5 compressor drives, 6 ship propulsion systems, 7 and so forth. Several control schemes have been studied and implemented in the literature for multiphase drives.…”

“…Large power induction motor drives generally require converters that use high‐frequency, high‐power fast‐acting semiconductor switches, but such topologies are either expensive or complex in implementation.
